I have been reading experiences for a really long time. I can say UWSA2 predicts for 90% of people. I feel UWSA2 is much better predictor of real deal than most of NBMEs.
I also noticed it predicted only when taken in last two weeks. Just my observation and opinion.
Just go back few pages and check yourself.
Again just my opinion. I hope I get good scores on UWSA2.
I am jealous of you (230 on UWSA2) !!
