Barts - didnt you run this query for me a few days ago--+500 and +600 teams last 10 games of season...no real evidence that under was the way to go (even though that was my thought as well)
Yep, it didn't really show anything for recent years other than in recent years, with two .600 and higher teams playing each other, the home team had an edge. In earlier years, under seemed to do better.
Here it is again, by season
H and 70<=(wins+losses)<=80 and 70<=(o:wins+o:losses)<=80 and tA(W)>.6 and oA(W)>.6 and season
