Slop was a poor choice of words, maybe flex describes it better?

It appears you're putting more concern in to this than what problem
exist. My wings and control system are standard plans built, closed
loop cables / pulleys, bell-cranks/ stick assembly, etc. There is such
a thing as "build up of tolerances" where the "tolerance" at each
location adds up to an unsatisfactory total. In our situation I think we
can accept "microns" of tolerance.
The primary source of lift on the wing is the low pressure on the top
surface causing the standard atmosphere pressure on the bottom to be
greater. We call the result "lift". My ailerons are rigged to match
the cutout in the wing from whence they came. I can not detect any
change in flight of the ailerons going out of rig due to the lift being
created. Remove as much "play" from the system as possible, rig the
ailerons correctly, and go fly.
If micron dimensions are a concern, don't go to the airport and wiggle
control surfaces on the Cessna and Piper aircraft on the ramp. It might
scare the hell out of you. Concern is good. Unnecessary concern can
keep you grounded.
