The is more the constant laying on the limiter vs just touching it prior to switching gears.
Drift cars and the like is a perfect example. On all my SRs, reving to 7-7500 RPM track day cars (300-360+ WHP) and touching the limiter (and just so on most shifts unless short shifting) I have yet to break a rocker or spit out a shim. This is with Spark Cut limiter (hard cut) and progressively cuting each cylinder in 100 RPM increments until redline (so cylinder 1 cuts @ 7100, cyl 2 @ 7200, and so on). This is very similar to a stock SR ecu logic. Never an issue.
The only folks I really se spitting shims are ones which lay on the limiter.
