It won't go through the same length of open loop enrichment that you experience from a cold start, because the ECU uses the coolant temp to set that condition.
My car remains in open loop for three seconds after a warm clutch start. But what you described makes me think it may differ from car to car.

I'm just trying to do a little math and see if it would be more beneficial to P&G with engine braking or EOC

P&G with engine braking isn't P&G, and I'd be surprised if you weren't getting
lower fuel economy than if you just cruised at a constant speed.

Sounds like a plan.
