CP, actually I forgot, but it is very likely a "trimmed" mean, so long as there is strong growth, the top/bottom days get dismissed in a time-series before the average is computed [this is to catch days also where stats fail and the next day double results are reported. This noon hints at pushing for three-quarter million validations [noon shows 371,339], and it's only Sunday. The 0.75M would thus by anticipation, be excluded from the speed calculation... but, yesterday full day led to a drop from 688 to 638 ;P

(Got an announcement note showing in my v7 client on this new venture, so the word is arriving to any v7 client that has WCG attached. Expect more Spaceball effects to kick in)
