Frankly,
there is absolutely no "chop" which is operationally significant to ATC. We
could care less. We care about the buzz-word "turbulence", not "chop."

What is the difference to you (at ATC)? I always understood "chop" to
be rapid bounces, and "turbulence" to be slower bounces. You could have
(for example) light turbulence or severe chop.

Do you not read the words that way?
