My point are your paragraphs of "subliminal messages" such as "you are going to kill yourself", or to crash water/land, or whatever. What can happen to me in the mountains, the same can happen to you in the city, or in a "perfect flat" rural farm when at the very last moment realising there is a powerline in front of you...
My apology for returning those messages back to you, but we all know what can happen when the engine stops for real.
Stopping engine for real, and on purpose, to establish a speed which varies +/-5 kts from POH depending on circumstances, is again beyond my comprehension.
