Bah, I had to come back...
First off, like dalter said, unexpected is not "out of the realm of possibility". Unexpected outcomes happen all the time (again proof that you need to study probability). Shooting .600 for a half is NOT unprecidented. He was spot on regarding the true culprit of the spread as well.
"Clark's HCA was worse than pitino's team's HCA...Clark was a C...Lane was a B...I would expect Pitino's team to play better at home than Clark's would/should at home...something you're not considering when you're just looking at the fact that Clark is at home."
This again shows your weakness in understanding both the engine and general logic. You say you would expect Lane to play better at home, but are apoplectic when they do. So they had an outstanding home half, that's it. When you look at Clark's lower HCA, you can't just look at it as a smaller advantage, you have to look at it as not only Clark getting more home support, but Lane loosing that home boost. They are two differant modifiers.
