Only half the projected classes into August have been awarded. So the next vacancy will be at least 2 more classes for late August and 2 in beginning of September. Last upgrade vacancy was 32. 4 classes of 8 would also be 32. But they change it up every once in a while. Upgrading 8 per week until mid November, then for attrition after that. Remember though, compass cut a few upgrade classes out of April, may and June. So they'll need to make those up before he end of the year too.
