Of course it wouldn't be very practical, and it doesn't fit very well with the stuff from TOS. But if TMP was on stardate 7400, that would put it 18 months after Turnabout Intruder, at stardate 5900. Cycling back to zero after 9999 would put TWOK's 8100 less than 11 years after TMP (which is pretty close to the official dates), and 15 years after Space Seed (3100).
I'd actually say it does
fit pretty well in that sense. Not to mention having TOS span stardates from 1300 to 5900 would be just perfect for the 1000 SD/yr model...
Alas, even if we ignore TAS, the other TOS movies are the weak point of this model. And 18 months between "Turnabout Intruder" and ST:TMP is enough for the refit but not enough for Kirk sitting behind a desk for 2.5 years...
