HW tournament statistics analyzer.

Now, the question is: do the starting games that were in the "spreadsheets" refer to games before the Nitro rating began (i.e., before September 2014), or even earlier? Could it be that the initial data imported from the "spreadsheets" already includes the results of games that are currently accounted for in the Ihromant rating up to September 2014?
P.s. I probably didn't explain it very clearly, but I did my best.
Judging by the fact that Zloy_romantik's initial rating in the Nitro rating in September and Ihromant's in February are the same and equal to 1431, it is most likely the case.
