ColonelCrockett: she lost 39 points ... which is more than she would have lost against someone within her own bkr range ... but not that much either .. she will gain them back again ;)
you challenged her .. she accepted .. she could have declined .. she could have won because you were inexperienced but appearently you were playing very well :)
the amount of bkr lost/gained depends on several factors :
the difference in bkr between the 2 players
the amount of games played by the player
the variation in winning/losses (deviation)
and maybe some more factors?
i assume you are talking about your game of jungle with volant ? as you had not played a game of jungle before your bkr was at 1500 (i think?) which was more than 400 points lower than volants bkr at that time ... 400 seems to be a break point .. when the difference is more than 400 the gain/loss in bkr is even larger
