Another thing to consider is your subsequent NR relative to the cab versus terra firma.
Having a TR lets you "wind your way into the sky" - lack of a TR unwinds it relative to terra firma but not the cab.
A rotation of 1.5 turns per second = 90 RPM which in the recent AW169 incident would equal 26-27% of your NR!
Your face mashed into the panel or the windscreen may be the least of your problems by then!
It is most important to not let the rotation develop. This enhances self-preservation!
I have experienced TR drive failure simulation (level D manufacturer owned with manufacturers data but appreciating the caveats.)
OGE Hover 2000'.
Aircraft with collective mounted throttles and a very large fin (EC135) - no briefing or forewarning and average ability on my part - recovered it but saw ~ 200' on the RAD ALT.
Most of todays machinery with skinny little pylons to enhance TR performance - good luck getting it straightened out with forward speed. You will need a lot of room on your side.
IGE - chop the throttles (if you can) and hold it off as long as possible. If you cant chop the throttles just plant it. To quote Sasless - ATT!
