Here's what a bunch of us swimmers were able to come up with as a projection for Jan - Mar class numbers as of today.

Assumptions:
50 class slots per month
Compass holds back at least Jan and Feb
Mesaba does not hold back
Endeavor SSB hires entitled to 1/3 the off the street slots per month (max 12/mo)
Furlough recalls completed in December - none in Jan

Here goes:
9 Mesaba +12 Endeavor = 21 slots/month
That leaves 29 per month for true off the street
58 in Jan and Feb combined
87 by March if Compass holds back the full 90 days

Once Compass flows start in, 7 Endeavor and 14 true off the street/mo

As of mid Nov approximately 100 true off the streets are in the pool

If anyone has different numbers or assumptions, please cite a credible reference.
