FFF,
I am so glad that you asked this question because I suspect that many of us have this problem. I certainly do and it is compounded by the combination of turbulence (high approach speed) and obstacles requiring a steeper than usual approach.
In my case, this causes a more sudden transition between looking at the flare point and then at the end of the runway.
In my gliding days, at Dunstable, we were taught to follow the ground but you cannot do this by looking at the end of the runway. It's a lot easier in a glider too. We used to laugh at the many aborted attempts of GA pilots trying to cope with the severe changes of slope.
I hope that we can get some good advice here.
