Demand calculation

So I have this flight that leaves MAD at 2:37 and arrives at BCN at 3:36. The thing is, demand calculation at MAD happens at 3:35. If my calculations are correct, and under the assumption that only flights that arrive within 72 hours get bookings:

Let's call D0 the day of the flight.

At D-3, 3:35, the flight receives no bookings as it is still 72h1m until arrival.

At D-2, 3:35, the first booking cycle happens.

At D-1, 3:35, the second booking cycle happens.

At D0, 3:35, the third booking cycle would happen, but by then the plane has already left!

Which means the flight will only get 2 booking cycles instead of 3 (obviously, I'm not counting connecting flights or ground transport here), and that I should move the flight 2 minutes earlier to get more bookings. Is this right, or am I missing something?

Thanks in advance.

It is correct.

you may want to increase speed of the flight so you get in two minutes earlier.

Thanks, no need as there was still a slot open.  :)
