That is correct, Fillion and thank you for providing up that info.
I do have doubts about the stated time on ground in DME which I believe was longer than what is stated (taxing in and out was absolutely long also given the situation...). But either way, the difference would be of about 30 minutes.
It is a dubious situation where many factors are at stake.
The whole point of this thread was to fuel true and interesting debate to demonstrate precisely how tricky of a situation it is. And you might think it's not important to discuss it, but I can assure it is because it might avoid people, especially cc, from making the same usual judgements right away and feeling (even more) devalued... It would have been an interesting discussion on the day and I believe it would have been useful. But I guess it's easier to ignore 26 tired, cranky and overworked cc and just tell them off with ''it's legal, ok?''
Anyways, guys, thanks a lot for the all the input and wish you the best flights!
Fly safe!
