According to ST's current seniority list, junior CPT is 1802 (ANC M1F) and first guy from June 14' class is at 2288. 486 numbers. The guy who mentioned the 300-something to me factored in his guesstimate of bypassers. His argument was that the percentage of bypassers increases as seniority decreases. I verified those numbers but got strikingly different results:

Next 100 senior to 1802 = 11 cpts, 89% bypass
Next 100 = 15 captains, 85% bypass
And so on = 25, 75%
34, 66%
49, 51%

Applying that in reverse from 1802 and keeping a fixed 90% bypass rate:

CPT is 48.6 #'s from 1st 2014 newhire and 88.7 numbers from newest guys on property (2689total-1802 = 887 numbers from list plug)*.1 = 88.7). Even though it's just a limited model and in no way will it predict future bid outcomes, the data does hint at how places like DAL and FX (and presumably us too?) can have such quick upgrade times.

Other observations poolies may find interesting:

List is just an RCH from 2700.
401 newhires since hiring resumed in 2014, previous class was NOV 2007.
222 newhires in 2017 so far.
In last 2 classes, every domicile and every a/c was awarded. Seems there may be 3-4 month waves where they alternate between heavy amounts of domestic and then international (M1F & 74) awards.
Last class in 2014 was August, 2015 had a September class, 2016 was back to August. 2017?? 78 more guys to reach 300.
