It uses the informations of the current draw (the one to coming at the current day id) to compute measurements for that day id.

What this issue does is that it shifts the correspondance.
Instead of having on day N (when draw results of day N are not out): the computation using data up to N-1.

It does instead the following (wrong way to do): on day N: the computation using data up to N
