Hi ElMaestro!

Thank you for your quick reply with my attempt to answer the questions:

I was told that this design is standard for this kind of studies (one test and 2 references) and I think that straightforward doubling the sequence was intuitive with the aim to decrease the number of subjects (no power calculations available)

No idea regarding the intra-subject variability but this information may be important for planning upcoming studies

Scaling would be definitely an option if it turns out that the CV>30% (it's a NON-GXP study)

hope this helps

Martin
