Roger,
I reckon Aimpoint has probably found your problem. You want your instructor to keep the "patter" up all the way to touchdown, basically doing the thinking for you while you follow his or her instructions. Gradually the instructor can wean off the patter, handing more over to you. In effect, you 'download' the patter your self (in your head) and it all comes together.
Its been a while but my approach was to patter.......... keep the descent coming on....... looking good............ gradually bleed back the power now as we approach the threshold....... start to round out to straight & level with gentle back pressure on the yoke........ now eyes on the end of the runway as you gently bring the power fully back to idle & raise the nose gently to the horizon & ...... keep eyes on the end of the runway as you feel the ground come up around you...... keep raising the nose with back pressure, back, back ........ well done, beautiful touchdown!
(Why its almost orgasmic!!)
Remember, make the aeroplane go where you want it to & feel the aeroplane through the air. Sense the ground in your peripheral vision with eyes at the end of the runway & you're there.
