It's going exactly as expected. It will be a dynamic manoeuvre, you know you will need to be working at a decent pace.

As the VFE speed is approached, say around 190 kts, the flap handle is moved to 1+F and the auto thrust will continue to accelerate the aircraft to 210 kts (215 - 5). At 201 kts and above the overspeed warning sounds until the flaps are at 1+F.
Don't wait until VFE to retract the flaps. Taking your example: F speed for an A320 @ MLW will be around 150 KTS. You can retract to 1+F as soon as you level off (SRS to ALT*). Plenty of time before overspeeding. S speed will be around 195, 20kts to go before overspeed, and even then, if both mess it up, auto retract will go to F1: auto retract kicks in at VFE-5 (210), 20 more to go to overspeed.

I just don't see any reason to do anything different and potentially get into trouble for doing something non-standard in a standard situation
