Zeke,
Around here they use swords, apparently its more hygienic
The 2 sec time delay which you are talking about still exists, it is added after the demonstrated spoiler/brake deployment time, it allows for a full braking configuration without getting deceleration credit for it.
The certification standards are black and white, which is why I mentioned an engine failure 1 second prior to V1, that allows for V1 / Brake application to happen at the same time, followed by throttle chop and spoilers. Now even allowing another 2 seconds as I explained above, there is still a chance that you will go off the runway.
Towers has already talked about tires, add to that rubber deposits, worn brakes, contamination, slope and we end up in the gray world. But how far do you go to account for this gray world, how far do we go to satisfy the legal world?
Anyone care to give us a legal impression on this?
Mutt.
BTW, look out for 777av8r, he has moved from my part of the world to yours.
