But every aircraft I’ve flown, the performance figures are based on being at Vref at 50ft and some unspecified lower speed at touchdown, so effectively you are keeping the additive with that technique.
All types are also equally vague about when/if you are meant to bleed the speed off. But since the way we plan flights you should be able to land with zero headwind then additional airspeed is not an issue from a performance perspective - the logical basis of gs mini on the Airbii. So it comes down primarily to the handling of each type whether it needs the speed bled off or not.
