ok, just tried quick test again.
In the first pass i use rockets, CCIP accuracy: ok!
Second pass with gun, accuracy: ok!
Third Pass with rockets accuracy: ok!
Fourth pass, rockets: now the CCIP pipper became less accurate (impact slightly on the right respect to pipper).
Fifth pass, rockets: same behaviour, CCIP less accurate
Last pass with gun, accuracy returns ok again.
My sensation is that some high G manouvers tend to influence the CCIP reticle accuracy
I've attached my track file. CCIP accuracy test.trk
