Here goes my point of view regarding Slick questions to Hudson.
When rejecting a TO at 115 Kt and ATOW 40T using 70T speeds, I´m absolutely sure that the airplane will came to a complete stop within the ASDA,cause the runway is enough for a RTO at 120 Kt and 70T.
When climbing at V2 of 70T instead of the real 40T, my climb gradient will be higher than minimun 2.4%, cause my weight is 30T less.
All the above will be true as far as 70T is not greater than RTOW for the airfield conditions.
Sorry my last post was useless. All questions were already answered. I didnot realiced there was a second page in the thread. Regards
