Right now KSU is 9th in the Asun in Massey and Pomeroy, and 8th in Saagrin (1 point above Bellarmine).
The rankings are certainly not perfect, but they're the best we got and I'm glad they exist. Carrying out the ratings to 2 decimal places implies a level of precision that doesn't exist.
At the risk of oversimplification, while you have a lot of objective data entered in to the computer, it is ultimately analyzed on a subjective basis.
I agree that "right now" KSU should be considered the worst team in the ASun. I'm confident that by year end (assuming they play a full schedule) they will be ahead of Bellarmine with a real possibility of passing others.
Spesaking as to the difficulty of ranking new D1 teams, and the inherent inaccuracies in the process, have you noticed the disconnect between Sagarin and the other ranking services re Bellarmine?
