P10 and P5 are computed the same way, P10 is based on the last 10 games while P5 is based on the last 5 games.
PSX is based on last 10 games and is more heavily weighted toward the starting pitcher.

I like betonline, but I like to run up and put down cash at Boomtown (local) sometimes, but like you say the lines are crazy, practically 30 cents sometimes.
