When do R160/R142 transfers update?

A scenario, to help explain my question:

• - You're sitting on the at Coney Island, it's a weekday evening, let's say 10:45pm. 
• - Conductor loads the to Astoria program.
• - FIND shows Atlantic-Barclays with transfers , , , , . , . as
  • • it has not passed 11pm, when  service stops, and
  • • it has not passed 12am, when late night services start.

However, by the time you get to Atlantic-Barclays, it will have passed 11pm.

Will still be announced as a transfer at Atlantic-Barclays?

• • If not, when will the updating of the transfers (announcements and FIND) occur?

1. 1. At the first This is announcement past 11pm
2. 2. At the arrival/doors opening of the first station past 11pm
3. 3. En route between stations whenever it passes 11pm
4. 4. At the arrival of Atlantic-Barclays

Thanks.

p.s.: I made several assumptions in my question, such as

• the conductor will not change the program mid-trip, and

• if the program self-updates, that the announcements and FIND both update.

        If any assumptions are wrong please feel free to let me know.
