Thank you for the explaination...Finally the straight answer I've been looking for.Here's the deal. The formula itself doesn't change, the #'s that get plugged in do. The handicap is based on the best 10 scores out of your last 20 matches (in 8-ball, 12 of last 20 in 9-ball).
A member on my team was 17% win last session. This session, he won his first 2 matches against 2 threes and APA bumped him up to a 4. Was confusing to say the least. He doesn't play safes and the innings are always high. Hell he can't even beat the threes on his own team.
I will be looking at the past score sheets for some answers...
