I don't see where the v3.44 has any Validations on my Box's, their all just Pending so far ... ???
I don't know all the BOINC rules for the processing order but some resends that went to dcushing* have already validated on 3.44. It could be that the lower WUs jump the queue? We're still 20.5k behind on validation. At the current rate it looks like another 24hours to catch up.
For your userid and 3.44 I show 1002 WUs that have validated successfully thus far. (Manual SQL query with the userid, app_version_id, success outcome, and validate_state valid)
