I have been sitting in the wings quietly reading this thread. I have nothing to offer in the way of expertise in this area other than having trained on many of the common avgas powered light twins (PA23, PA30, PA31, BE76, Baron, C310, C402 - I have no turbine time) and undertaken many IR renewals in same.
I have only flown these activities with very experienced and highly regarded instructors.
I cannot recall an engine failure on take off having ever been simulated other than by using the mixture control!
