777indubaiboy, some points regarding your post:
"This stupidity came from the VP of Aviation medicine Dr. FR."
1. Complete your pre-slander checklist. I think you'll find that decisions such as these are made at a much higher pay grade than VP, and aren't even initiated in the medical department.
She has been asked by the other docs to provide clinical evidence and is struggling to do so.""
2. Try to make sense. Clinical evidence of what?
"Please write to your fleet managers and ask them what the evidence is. They don't have any."
3. See point 2.
Leaving aside your flawed post; try to read between the lines; For the purposes of statistical recording the important trigger is the number of SKF occurrences, rather than the duration of the SKF.
I suspect in practical terms there won't be much difference to the way the docs treat fatigue - you will get your 2 days SKF, then the appropriate number of SK days after that.
I agree with nolimitholdem, smoke and mirrors or just another consequence of having too few pilots and trying to make the numbers fit.
Remain calm.
