Provisional Ratings
Posted: Sat Jan 04, 2014 1:57 am
The EGF's rating system has no concept of provisional ratings - should this change? A player who enters the rating system may enter with a grade (and thus rating) which is wildly inaccurate, and can thus safely and wisely be changed after say 10 games. Sometimes a rating reset could do the same thing, but of course this only works in one direction, and it leaves intact the initial results.
Take this year's London Open, where a player called Tethys entered at 19kyu and won all their 6 games. They had no previous entry in the database, unless they previously played unbeknown to us all under another name. By the way, the grade of 19kyu was probably chosen for them by substracting 2 stones from their OGS grade. Given that they boosted their rating by over 400 points, it seems plausible that their entry grade could then be adjusted retrospectively.
