Thanks for that. Do I understand from all that, that basically there is an additional safety factor in normal V1 and Vr speeds that can be done without when in a tailwind situation?
This all came about after looking at AGP Rwy 32, but when I looked deeper for interests sake, it also seemed to the case when operating out of unrestricted, hugely long airfields where there was no apparent concern with second, third or fourth segment performance... hence the conundrum! Maybe it's just that they automatically remove the safety margin whenever there is a tailwind, regardless of where you are.
