I have over 300 games now with all 3 versions and the results show Beta 15 points above Preview 2 and Preview 2 10 points above Beta 7. Even my 300+ games are not enough to be sure but it looks like the new time management has a slight negative impact on the blitz strength. I don't like giving up even 25 Elo points. At the top level they are all precious. Note I have not tested the new "slow" time management function.
