Whatever happened, major kudos to the crew!
way back when I was in the USAF we had 'minimum acceleration checks' which have never been used in the airlines or gen av to my knowledge. However, I began timing takeoff and all things being equal, from time of application of takeoff thrust (including using reduced thrust when applicable), you are rotating after about :30 seconds. If you go beyond that, you are heavy, it is hot, it is high, the runway is contaminated or a combination of all. At DIA and ABQ it was not unusual to have a takeoff roll of :45 seconds or greater.

The question is.. why the abort after V1.
