Let me ask you a question? Why would you need to pull the last 3rd notch of flap at all or at minimum till your 50 to 100 feet and assured of landing ?
The only time I can think of is if you are high, need the drag to fly a steep profile onto the runway landing spot.
Yeah look, i can only agree with what your getting at, the need to pull on full flap earlier than you suggest if at all, means you are basically abit too high at that point and need to dissipate that extra energy over the same ground track to the runway.
The session of circuits i mentioned in Feb where it was BLOODY HOT was a good case in point.
(Under the bubble canopy in the Sporty is like being locked in a car in full sun
)
I was flying the roughly the same circuit track across the ground as i'd done previously but we just weren't coming down, so at least initially we needed full flap. After a couple of circuits we could make those adjustments extend downwind which allowed a greater distance traveled to lose the same height.
But the hot weather and thermals still caught us out, one approach that stands out i decided not to go to full flap but consequently we arrived at the threshold a shade too fast and so i got some extra practice holding off as we floated an extra 100m down the runway - still landed with plenty to spare but the difference was obvious.
The more experienced operator than myself could possibly anticipate those conditions adjust to the situation accordingly and get it spot on first shot.
Hence
achieving proficiency in any skill which increases your options should you find yourself in such a situation will, IMO, only improve safety.
At this stage i'm happy to say my experience is very limited, but in contending with those adverse situations in a controlled way i'm earning the confidence and skills to deliver under pressure when the need arises.
In that sense it's not my best flying that i'm trying to improve, but my worst
