Why are people saying to wait a few days or weeks for the SERPs to adjust? Why would there be adjusting? I don't see how Google didn't do a lot of testing before this release, why would they need to adjust anything after?

Go back and read through the old update threads...
This is more of an 'old school' update than what we're at all used to seeing lately.

My guess is this update was so big they had to pull some of the filters and systems off and we'll see adjustment over the next days possibly weeks. (If you go and change something now that would be corrected in a few days you might 'fix' your site right out of the rankings.)

They used to do it that way most (all?) the time for larger updates.
