wordpress.com stats on 2.8

It seems like newest rev of wordpress stats has done some recalibration that now more closely match performance of Compete stats after its recalibration for June

Both wordpress stats and compete show more than a third less than statcounter which had been in synch with both prior to a) wordprtess 2.8 and most recent wordpress.com stats 1.4

Has anyone else seen this marked change or did everyone just go on vacation?
