Has there been some change to the poll metrics that I didn't hear about? I've noticed in Rupp it seems to be much more volatile than it used to be.

Examples: undefeated top 5 team loses to #1 by 3. Next day: unranked. Team not getting votes goes 4-0 and jumps each day until they reach #6 after the 4th game. They lose the next game and the next day: unranked.

I'm not making a case here about whether any of the teams deserve to be ranked (the second team is mine and with one Sr., they are not a top team by any means) but I've never seen so many new teams in the top 25 every day and teams rising and dropping drastically with every game.

Did I miss a change here?

Yes Seble said that rankings would be volatile, especially in the early season. Should calm down at the end though. 

Starts out based a good bit on ratings, and as the season goes on actual record has more and more weight, I think.
