given available info, one can sort of figure it out.
at GSPF may 2018, kayte stated that upon returning to benton they would sign off on currently completed TNAs that would bring the total out the door to 200. the numbers going out right now appear to be filling in the high 200s.
gotta give spooky credit for completing the first ~300 games by month end, and ill even bump it another 20 for an argue free/'be nice' cushion to 320. this means ~120 games were built during the 4 months jun, jul, aug, and sept; which works out to ~30 games a month, slightly higher than the 25 per month for the first 8 months/200 games. considering ACNC apparently wasnt on the line during most of that time, the combined TNA+ACNC production appears to have fallen short of the 50 gms per month [25 every two weeks] they had hoped to reach over the summer.
the end of the sept also signifies the end of a calendar year in which production was in full swing. TNA#1 was delivered mid sept 17 to ed robertson. allowing a grace period of two weeks to 'ramp up', we will use oct 1 17 as a start date for TNA production. one full year will end in ~two weeks, on sept 30 18.
looks like ~320 TNA, plus whatever number of ACNC get shipped in the next two weeks. so, low to mid 300s for the most recent 12 month period. to put that in perspective, how many days does stern have to be operating to match that, like 7?
