Here is the average turnstile counts for the 3 new SAS stations for 24,27,28 Feb ,1,2 Mar 2017, as per the turnstile counts from the MTA website. This is the last of the comparisons, I plan to file. It looks like the averages are pretty steady.

Enter: 64,526
Exit: 52,318.2
Total: 116,844.2

For comparison purposes here are the average counts for the 4 Lex stops from 68th through 96th for the same time period.

Enter: 124,801.6
Exit: 94,990.4
Total: 219,792

And the same totals for the same 4 stops from the same week in 2016.

Enter: 170,950.2
Exit: 120,488.4
Total: 291,438.6

For those who are arithmetically challenged, here are the differences:

Enter: 46,148.6
Exit: 25,498
Total: 71,646.6

According to NYMTC's 2015 Hub Bound Report the 8-9 period accounts for roughly 12% of the 24 hour total. Applying this statistic to the data, the peak hour saw approximately 5.7K fewer passengers. According to NYCT loading guidelines, this could be handled by 6 more locals during this hour.

The same NYMTC reports show that 21 locals ran during this hour. Adding 9 more locals during this hour would bring the service level up to 30 tph. That's well within the system's capabilities.

I posted a cost estimate for added Lex locals vs. the reduced cost for operating the current amount of Q's passed 57th St. It will still take roughly 1000 years to recover the SAS cost.
