Chaps, Tee Emm's OP was a fair introduction.
You might disagree - and that's fine - but can we play the ball and not the player, please ?
All engines out is an interesting exercise in competence and self confidence. I've seen folk in the sim make a hash of it, do it well and, in the case of one airline group I recall (Chinese - most, and probably all, ex-MIL) who had no standardised technique, all did it differently .. and every one of them got in just fine first time around (some tidier than others but, nonetheless, all were successful).
The fact stands, though, that a practice exposure in the box is cheap insurance for a not very common .. but certainly not rare .. occurrence.
