Strange as it seems, the system thinks BBC isn't playing as well as they should be and this is because they have been over matched and the calculated spreads were much higher than the actual scores. This was noted last week and a new set of logic was included to address the fact you normally can’t win by 100 points in 6-man.
It will be applied after week8 when we regress all the game again using the current power as the initial starting point
AHC has on the other hand played some good teams and has been rewarded. In this system it is possible to win and lose power or lose and gain power.
