Hi Seb, I have just performed a little clean up of the "Consistency testing" chapter of the relax manual. This is now in a pretty good shape to ship out to users. I was wondering if you'd like to add some small text as the end, a last paragraph maybe, explaining why the script generates the F_eta and F_R2 values. From reading the references, this is obvious. But if a user reads this chapter as it is before jumping to your papers, they will be confused.
