Congratulations, The Pack. Will be interesting to see the scoreboards next month which will reflect these challenges. At present there is a Big Eight group of top clans with The Pack a bit behind them at 10th. http://www.conquerclub.com/forum/viewtopic.php?f=438&t=147062&start=105#p3242101
If The Pack wins by merely 50% margin against GR (933) and OSA (902) then The Pack gets 933 + 200 = 1133 and 902 + 200 = 1102 as additional basis points (which are weight-averaged together to determine rating). Since The Pack is currently at 1151, this would bring them down slightly as these numbers are lower than their present rating. But if The Pack wins by 60% margin, they would instead get 933 + 200 + (10% * 2) * 400 = 933 + 200 + 80 = 1213 and 902 + 200 + (10% * 2) * 400 = 1182. This would bring them up slightly as these numbers are above their present rating.
