Easy incremental weekly similarity investigation after each exercise round

[markkuriekkinen]

Radar seems to be currently designed for investigating similarity in the end of the course. It should be easier and more convenient (i.e., need better user experience) to investigate the situation weekly after each exercise round.

It is important to investigate how Radar actually works and how feasible it is to check the situation weekly. Is it necessary to always re-run comparisons for old exercise rounds that have already been closed or it is enough to run the comparisons for the new rounds that have just closed? Does the graph view show up-to-date data every week so that we can see after closing a round if new student pairs pop up that have been copying solutions for many weeks?
