be vewy vewy careful
Been a few years since I set foot in a Pa44, but is the technique in the flight manual? If so, fine, if not be very very careful, cos if you get it wrong, even just a bit and can walk away, then you might have some serious questions to answer.
The other thing to remember, presuming that it's a technique in the flight manual etc, is that it does not get you to the single engine best rate of climb speed any faster. Infact the opposite might be true.
