Hi,
The Review Cycle appears to be date driven based on Submit date.
The oldest Submit date I have that is "Pending Review" is 03/01/2015 (45 days) as of today.
What is your oldest Submit date that is "Pending Review" as of today?
From what I have observed...
Over the past 6 months the process has been linear and has been a revolving 45-50 day cycle from the Submit date.
I just had a group of logos cleared out from backlog... the last logo completed on Sunday 12th (2 days ago) from my prior "Accept" batch.
I anticipate we should see a Review Cycle this Thursday/Friday on BrandBucket or sometime close to those dates. The trend has consistently been as a Logo Queue "clean-up" process is completed, it is immediately followed by another Review Cycle.
So... every time I see my Logo Queue "cleaned-up"... I start voting to build up Credits, get ready for another Review Cycle email... and sure enough... it shows up within 5-7 days later... and the cycle starts again.
I hope the overview is helpful...
