Hi Helmut (and ElMaestro - sorry to post in this thread, but all your answers are great!),

❝ Of course, ElMaestro is right.

There Can Be Only One.

OK, I understand the logic here.
take a look at some (theoretical) situation: a Sponsor goes with Potvin C (don't ask me why), moreover, he proved that with the current CV and n1 T1E does not exceed 5%.
But as you showed in the lectures and in example above, Potvin C could not ensure 5% for all combinations. Thus, during stage 1 the CV was lower and the resulted T1E was out of 5%.
What would be the right (safe) way out in such situation?

Kind regards,
