Just one more comment:
It is all fun and games discussing VRS here but:
After the debate of best practice for avoiding VRS, Recovering from incipient VRS and recovering from fully developed VRS.
It is imperative that you have a proper technique in your bag of tricks.
If you encounter VRS in any state there will be no time to have a debate with yourself as to what you should do before things go from bad to awful.
Have a plan in place, carry it out.
Even if you just suspect you are entering VRS recover to a safe flight regime immediately.( IE Forward speed, altitude level or climbing, Power and RPM in limits. )
Fly safe everyone.
