I wouldn't exactly call 21 "crazy low." It's two days after the New Year. People are still coming off holiday schedules. Even if it's 21 per class for the three January schedules classes, that's 63 numbers of seniority gained in one month. Under the average attrition rate and flow contract, that's still +40 for the month. People leaving above you and coming in behind you (relative seniority, of course).

Not sure why the cause for concern, but I'm pretty happy with it..
