.. in which case you should be able to quote from the user manual what the basis for the two calculations might be .. and that might give us a chance to offer pertinent comment ?
Both examples limit code was F, which is field limit. I dont know if the operator forces changes in V1, but I can understand that they may wanted always a difference of 2 knots between V1/VR, it could be. I can understand what you say about basis of calculations and indeed it doesnt make sense to try to understand those things.
The 737 example is invalid, that is a 737 and it behaves like a 737, not a 747. You will find that aircraft with more than two engines do not suffer as drastically from greater flap extension, as two engine aircraft do.
It was not an example, this thread is very old and I found it by searching about flaps and ASDR. Because the subject was relevant, I wrote my question here. (You can see 6 years difference between the last post and my first post here!)
