FFF, something to think about is the discussion that has gone on here before about where to look to judge the round-out/flare.
You no doubt remember the postings of Chuck Ellsworth on this subject. Actually, in a more recent thread I recall you summarising the early postings he had made, where you discussed the fact that the different parts of the approach had different names and that was the cause of some of the confusion (I can't find that thread right now unfortunately). However, I think you actually misquoted him in that you said once you agreed that you were talking about having reached the flare point you transition your viewpoint to the end of the runway. (As this is from memory I apologise if I've misrepresented the posting you made) He actually said that was absolutely the wrong thing to do. And with Elstree's upsloping runway the problem is even more marked. Instead he recommends about 500' in front of you, if you're landing at around 50-70knts.
All my flying has been at Elstree and I'm not sure precisely where I focus when I'm landing, but on neither runway is it the far end. Solving your problem isn't made any easier by the fact that you can't fly circuits at Elstree, unless you do so with a resident instructor (and then only one from Cabair or Firecrest).
