Never understood why you wouldn't just set FL100/MEA in the window straight away instead of setting something to come back and fine tune later. A few extra clicks is adding fractions of a second and by that time you should be on oxygen having completed the most vital and time critical memory actions anyway.
Yep - I my daily work I decided for myself to discard that piece of the procedure and always set a safe target on the first loop for exactly the reason, that there is a risk of becoming incapacitated. Usually its FL100 but before entering higher terrain I will brief my "first target" to the chap next to me...
I regard the current procedure as dangerous...
