Any OEI power above PC2 with calculated exposure is wasted, and could have gotten you improved safety
You should start a campaign to advise arline passengers that a well defined exposure during takeoffs and landings can produce much lighter airplanes with a lot less thrust, therefore less costly, that would save a lot of money for airlines but they (as passengers) need to accept the associated risks.
I really do not understand why in the helicopter world we should not try to achieve the safety level of the airlines, and I mean ALL. Safety does not come free and requires additional costs in all fields.
Engine failures are remote but happen and when they happen they cause fatalities.
