Boing FMC VNAV Speed Flap Selection Logic

Lets say a still wind day on a STAR using VNAV path with the speed intervene window not open (open would also make no difference to the logic I suspect)

The aircraft follows the VNAV path and begins the process of slowing the aircraft for flap deployment.

Does the FMC logic assume Flaps will be taken at limiting speed (say 250kts and decelerating in an 800) or at the up speed.

Hope that makes sense.
