Without a very accurate count of CJOs and class sizes (present and future), I don't think there is a good way to know the time frame with a high level of accuracy. Throw in a change to class sizes (which it sounds like just happened with classes going from 55 to 25 pilots) and a few deferrals and it gets even harder. When my group got job offers at the end of March we were told there was "little to no pool" and to expect first or second week of May. Personally, I am now anticipating mid-June as more accurate.
