Like you said in your post, there are times where I can land, and not
feel
the plane touch the ground, but lately, I think I am exercising the
strength of the mains. I use my G meter to evaluate my landings, and
even
though it did not register more then .5 G, I am sure I got some bad
"ratings" from the "landing judges" today.

As far as your question as to why, I think it's karma....

A few years ago my landings seemed to have gone to pot. Nothing I could
put my finger on, but I could seldom get it right. I thought I could
detect some
resistance in the elevator movement, and asked my mechanic about it. He
pronounced it normal. Then somewhat later I read an article about the
importance
of keeeping your control mechanisms lubricated - and took the advice.

Presto! back to normal. It really does make a difference.

Another thing is the use of flaps. My plane has 40 degrees in 10 degree
increments. I have found that it is best to reserve the fourth notch
for
those occasions when you really need it.
