Sorting Tables

v0.31

  • Added sorting by rank to score tables.
  • Show equal placings for airScore and Flight System rankings.
  • Corrected mislabelled column headers in the 2-way comparison tables.
  • Move the display settings to the settings tab and table.
  • Strip out FsCompetitionResults and FsCompetitionResults elements when trimming the *.fsdb down to ./.flare-timing/trim-fsdb.xml.
  • Use adaptive time checks to sort crossings when detecting taggings.
  • Use the give when detecting zone crossings.

Moved Working Files

v0.30

  • Moved the file .flight-system/clean-fsdb.xml back to the root folder with as *.clean-fsdb.xml. Moved the trimmed XML to .flare-timing/trim-fsdb.xml.
  • For comparisons, lookup pilots by ID and not by name.
  • When parsing extra reach from *.fsdb avoid zeroing it or making it less than reach.
  • Split fs-filter into fs-clean and fs-trim.
  • Split ft-fly-time from ft-cross-zone.
  • Invert the command/task folder order to have task/command such as .flare-timing/task-1/align-time/*.csv.
  • Break up working files so that they are per-task, not for the whole comp.
  • Create intermediate folders for workings, if missing.
  • Show the comparison columns in the table that goes with the time plot.
  • Parse //FsScoreFormula/@use_flat_decline_of_timepoints from *.fsdb and set the corresponding exponent as ^(2/3) or ^(5/6) for the time points distribution. Draw the corresponding line of this equation on the time plot.
  • Parse //FsResult/@points as double rather than int.
  • Parse //FsTaskShortestPath deep, at any level of nesting within FsTask.

Ess ≠ Goal

v0.29

  • Fixed a space leak and made some of the commands faster by making use of parallel-io and using pragmas; INLINE, INLINABLE and SPECIALIZE.
  • Removed the --dir option from all commands. The current working directory is used instead.
  • The mask-track command has been split up into smaller commands; mask-arrival, mask-bonus, mask-effort, mask-lead and mask-reach. Each deals with separate aspects of masking.
  • Avoid calculating impossible means when the data set is empty. These were seen as huge negative numbers before the fix.
  • Show the flying and scored fixes for pilots that have had their tracks downloaded for the map.
  • Show the effective reset in the penal table when the pilot is too early.
  • Move the penal tab to the top-level with its own children; Jump-the-Gun & Auto, Ess ≠ Goal and Manual.
  • Under Basis | Pilots, put each kind of penalty in its own panel.
  • Show toll, rebate and fee to explain how the points after applying the jump-the-gun penalty are not less than minimum distance.
  • Score the penalty for making Ess but not making goal.
  • Show tasks stopped and cancelled in the task list.
  • Only show the extra reach via glide column for stopped tasks.
  • Don't dislay a chunk distance in the effort table for pilots that don't land out.
  • Parse FsCompetition/@utc_offset whether or not it has a leading sign for both integers and floats.
  • Fixed a bug where looking up a chunk for effort failed because of rounding then the misplaced pilot got zero points for effort.
  • Only the *.fsdb and folders for track logs are left in the root folder since the input, output and working files of flare-timing moved to the dot folder .flare-timing. Likewise files for comparison have moved from the root to .flight-system and .air-score. Add a Compare top-level tab for the comparisons between scores.

Plot Selected Pilots

v0.28

  • Zero seconds per point is used by FS as a sentinel value to turn off the jump the gun penalty. Be aware of this and calculate the penalty only if the seconds per point are positive.
  • Select the last crossing of the last start gate for the start crossing.
  • Exclude start zone crossings that come after tagging subsequent zones.
  • Selecting table rows will highlight points for those pilots in the scatter plots.
  • Restrict function-plot to v1.19.1 as later versions introduce breaking changes.
  • Use square of leading area when calculating leading points except for:
    • GAP2000
    • GAP2002
    • OzGAP2005
    • GAP2007
    • GAP2008
    • GAP2009
    • GAP2011
    • GAP2012
    • GAP2013
    • GAP2014
    • GAP2015
  • Use positive numbers for demerits and negative numbers for penalties.
  • Build the comp server with cabal by relaxing constraints on HUnit.
  • Commands dealing with FSDB extraction already had fs- prefixes. Do the same for flare-timing, using ft- prefixes for these commands.

Weighted Leading Area

v0.27

  • Show milliseconds if a pilot jumped the gun by less than a second.
  • Display ###-pilot or ####-pilot dependening on the pilot id width.
  • Add a marker to the nearest vertex on the nearest track line when the map is clicked. Use the default marker for these.
  • Show all crossings in a layer on the map, the nominees. Use different marker icons for different items. Use unfilled circles for crossings and filled circles for taggings.
  • Pick the first crossing of the start gate taken.
  • Better detect whether a start is an entry or an exit.
  • Associate crossings with start gates and pick the last crossing of the last start as the start.
  • Show start nominee crossings for each start gate and the start crossing as separate layers on the map.

Leading Area Plot

v0.26

  • Show a plot of the leading area, selecting up to five pilots at once. Include the extra area added after landing and another potential area hinted at in FS code comments, the area added before the start. Show the parts of the leading area in the legend of the plot.
  • Show the leading area with thousands separator and units of km^2 s.
  • Show the leading area difference as actual value over expected value minus one.
  • Use distance or distance squared for the leading area.
  • Show a table of tasks instead of a list of tasks.

Open API Specification

v0.25

  • Added an OpenAPI specification (OAS) for the server.

Arrival Time Points and Start Too Early

v0.24

  • Score hang gliding comps using arrival time points.
  • Document for stopped tasks at least that unpack-track needs to be run before peg-frame.
  • Color code closeness to scores of FS in the task list using green for less than 2 points, yellow for less than 8 points and red for greater than that in the mean of the differences in the total points.
  • Do not default to award arrival position points when no kind of arrival points are allowed.
  • Award pilots without a tracklog effort for minimum distance.
  • Add a table showing jump the gun penalties and how fractional, point and reset penalties are applied and the final points are rounded.
  • Consistently strike out reach when the pilot was awarded minimum distance, whether that pilot had a track or not.

Jump the Gun

v0.23

  • Show the task number before the task name in the breadcrumb.
  • Allow early tagging if within the jump-the-gun window.
  • Don't show all the turnpoint names in the task detail if they will overflow the header.
  • Add a ruler to the map.
  • Use zones enlarged by give, the fractional and absolute tolerance added to a zone's radius to give some relief to pilots with vario inaccuracy.
  • Show the mean and standard deviation in the difference of task points compared to the expected points from FS.
  • FS renamed FsTaskShortestRoute/FsTurnpoint to FsTaskShortestPath/FsPathVertex. Updated the *.fsdb parsing accordingly.

Earth, Through and Through

v0.22

  • Use the Earth model and Earth math throughout the scoring.
  • Avoid skipping some B records (position fixes) when parsing *.igc files.
  • Show the effective inside and outside border of turnpoints with tolerance applied.
  • Allow a crossing if one fix passes the time check but the other does not.

Validity Compared

v0.21

  • Compare task validities side-by-side with those of FS.
  • Show the optimal task route from FS on the map.
  • Compare optimal task route from FS with those of FS in the Geo table.
  • Show the extra distance from glide above goal in the score distance table.
  • Compare reach and effort with linear and difficulty from FS in the score distance table, in the tables beside the reach and effort plots.

    └── penalty_points
  • Handle glitches in the ordering *.igc file B record times. Time is meant to only increment during the day as fixes are logged. Discard times going backward less than an hour and roll over the day when the time goes backwards more than that. There's no rule in the GAP document about this but that is what FS does.
  • Exclude zone crossings that fall outside opening times of the zones.
  • Workout task difficulty using relative difficulty from every chunk of the task, not just those where a pilot has landed.
  • Add score tables for effort, speed, time and arrival. In these, sort the rows by descreasing order of the relevant points.
  • Include the pilot race number with the pilot in each ###-Pilot column of tables.
  • Enlarge the split plot.
  • Squish and stretch the leading plot to make room for the width of the associated table.
  • Switch to using the B612 font, designed for use in aircraft cockpit screens.
  • Add fs-effort, a command line tool for extracting the landings, chunking and relative difficulties from a competition *.fsdb.
  • Show two more decimal places when point difference is +0.0 or -0.0.
  • Clean and trim elements and attributes of the *.fsdb before use with fs-filter, a new command line app that writes *.clean-fsdb.xml and *.trim-fsdb.xml. The cleaned file has sensitive information removed that would allow its publication. The trimmed file is the minimal set required by flare-timing, taking some data as inputs for scoring and other data for comparisons of the scores.

Stopped Validity and Bonus Reach

v0.20

  • Only consider crossings that are exiting exit zones and entering entry zones.
  • Compare arrival fractions between flare-timing and FS.
  • Show the working for weight calculations next to the split plot.
  • For paragliding, when the goal ratio is zero use a tenth of the distance ratio for the leading weight.
  • Show the stopped task validity.
  • Add plots for launch, distance and time validity.
  • Add a series of three plots for stop validity relative to mean reach, the spread of reach and the number of pilots landed before the task is stopped.
  • Peg the data frame for each pilot's track to the scored time window for stopped tasks.
  • When the task is stopped, add a bonus distance to reach. Glide from the altitude above goal to the altitude of goal for each fix of the track, picking the shifted fix that is now closest to goal as the point reached.

Making a Line Goal

v0.19

  • Sample line goals as semicircles when figuring out the optimal path.

  • Sort and rename the base layers of the map to:

      Task

  Path (planar)
  Race (spherical subset of path)
  Race (ellipsoid subset of path)
  Race (spherical subset of waypoints)
  Race (ellipsoid subset of waypoints)

  • Detect crossings of line goals.

  • Show the list of tasks even when task lengths have not been computed.

  • Show the task name in the list of tasks.

Interpolate Zone Tagging

v0.18

  • Find that GAP and FS use different equations for working out the speed fraction and leading fraction. Show the curve of the equation in the GAP rules but use the same equation as FS.
  • Add a column for leading area in the table alongside the leading point distribution graph and compare area, coefficient and fraction with norms.
  • When the HH:MM:SS field of IGC B records decrease bump the YYYY-MM-DD.
  • Don't apply give to exit cylinders as pilots often fly back into them to take a start. They're flown as both entry and exit cylinders.
  • When comparing data to norms, if the numbers aren't exactly the same but the rounded display of numbers are then display "=" instead.
  • Interpolate zone tagging and show pairs of fixes that straddle a zone and the tag point as separate markers on the map.
  • Draw line goals on the map as semicircles.

Side-by-Side Score Check

v0.17

  • Parse the *.fsdb for scores.
  • Add an Overview | Points | Speed | Distance set of child tabs beneath the Score tab.
