I don't think so, not in my testing. Arasan has a pretty good book, though. That might have influenced your test.

Maybe. In fact, it is just a single test match. Enough for me to appreciate the trend and the accuracy of the evolution for this new version. A precise calibration (which requires time and resources) is the job of CCRL, CEGT & co.
