Main problem with either time limit is the AFM limitation .. the takeoff thrust setting has to get you to the end of the third segment so there will be limits on the extent to which you can stretch the second segment. The extended time limit helps out significantly.
The Gulfstreams that have the 10 minute T/O thrust limit have a big advantage at Aspen, Colorado.
