Hi Helmut,

» lucid words about SF and great ideas about hacking embeded Linux-machines. :-D

Well, it's a proven solution (not by me!), just not quite legal in most of civilized countries ;)

» In a TSD we have some chances to demonstrate BE already in the first stage. Hence, my personal recommendation for n1 75-80% of the fixed sample’s n.

After playing with data from other studies, I've made a suggestion that same recommendation is good single stage cross-over with 2 groups to keep the study safe or "conservative"... We can then demonstrate BE based on larger (first) group if requested by regulators.

Regards, VStus
