i recently had some funky business with BKRs too: here are the results of the last four games of Froglet i completed, in order:

plaintiger: old BKR = 1700, new BKR = 1700 (0)
MsDelete: old BKR = 1301, new BKR = 1240 (-61)

plaintiger: old BKR = 1700, new BKR = 1700 (0)
Paula29: old BKR = 873, new BKR = 871 (-2)

plaintiger: old BKR = 1700, new BKR = 1700 (0)
TJ: old BKR = unrated, new BKR = unrated

plaintiger: old BKR = 1700, new BKR = 1707 (+7)
Lorraine: old BKR = unrated, new BKR = unrated

can anyone explain the logic behind this (without getting too much into mathematics, which will serve no purpose but to bewilder me instantly)?

why did i get no points for three wins in a row - for one of which my opponent lost SIXTY-ONE points, and one of which was against an unrated player - and then get seven points for the fourth game, also against an unrated player?

this makes no sense to me at all.

oh yeah: the ratings of the first two players were established (not provisional).

thanks...
