Swamp, what have you done with lucid, and why are you posting in his place?
OK, point taken. Still, if you use that term with a typical car nut in this context, they're likely to think about a tingle in the palm of their shift hand rather than a broken wrist.

I am also saying the large amplitude shifter displacement is most likely a function of how the engine/transmission is mounted. I made that clear in my previous post. Do you agree of disagree with this?

I absolutely agree. Thought I said that, but perhaps (what are the odds?) I used just a few more words than absolutely necessary, thus blurring my intent.

Missed that. Perhaps you used more words than absolutely necessary?
I distinctly remember having to reapply my ChapStick while reading.

Huh. Haven't sampled that, but I'll check this out at some point.

Can't speak with authority about what they had in mind, but rev limiters (of whatever design) are of course not rocket science.
