Ticket posting time stats
Looking at my last 14 posted trips (2 paid, 12 AGR, all NEC), here are the stats for posting times:
Average # of days: 6.9
Std. Deviation: 2.8
Median = Mode = 6
Minimum = 3
Maximum = 13
At least the stats are better than the promised "2-3 weeks on average".
N.B.: I think one or two old ones (plus two trips yesterday) have not posted; I'm too lazy to check now.
What kind of distribution is this? Perhaps more people could post their posting times...

Ah, when I throw out the ones over 2 weeks, remarkable in their unusuality, it is more prettily normal:
Min: 3.000
Max: 11.000
Ave: 6.930
StDev: 1.549
Median: 7.000
Mode: 7.000

8 45 40
9 15 21
10 8 7
11 3 2
(PredTickets is the [rounded] number of tickets expected if the distribution were exactly normal.)
A couple things to consider:

A couple things to consider:
- Thruway bus tickets take considerably longer to post (of my 5, Mean 29, StDev 8.6);
- Points post only Tuesday through Saturday, so if you travel a lot on Sunday or Monday, your M/M/M would be closer to 9 or 8, respectively, and the distribution would lopside higher, because you'd have no 7's and 8's, or 6's and 7's, respectively.
