Be careful if departing at high weights with an MEL item indicating flaps/slats slow. Under normal circumstances the lift devices would retract before you accelerated through their limiting speeds, however if clean speed is high due to an increase in weight its quite easy to be passing 215/230kts while they're still on the way in. In this situation select minimum clean speed and wait until retraction is completed before managing the speed.
If departing in the mid 70t range I brief to expect a possible auto retract of the flaps as it only takes a little turbulence or even a turn to trigger it. Flaps go up and barbers pole moves up no drama, though it is recorded by FDM. The reason is obvious in the case of a high weight T/O though at lower weights you may be asked for an explanation.
Auto retract is the reason some MEL items prohibit T/O in 1+F incase it gets triggered at an inappropriate time. There is no auto retract in CONFIG 2 or 3.
