Dear Helmut!

Parturient montes, nascetur ridiculus mus. Horace (Ars poetica, Ep.II.3, 139)

Full ACK :-D

As every Pythia's saying: Mysterious!
Nowhere in the scABEL method there is an term utilizing the 'uncertainty' of the variability of the reference.
Contrary to the FDA RSABE which has such a term.
That's the reason why both 3-period designs (TRR|RTR|RRT or TRT|RTR) require similar numbers of subjects.

And deeming 12 subjects as sufficient to 'control' that 'uncertainty' is at least strange (politely spoken):
CVCL(CV=0.3, df=12-2, "2-sided")
 lower CL  upper CL
0.2072921 0.5513299

From no widening up to cap on widening!

But the net effect is of course pleasing :cool:.
