      Finally became curious enough about this to look up its definition.
      (Never did know exactly what it meant.)
      And you know it seems everyone else on the planet understands perfectly what this means.

      So, when acceleration in a straight line from a stand still, how does 1 foot of rollout help with acceleration times so much? And what exactly does it mean? How is it accomplished?

      There's 2 beams, at the pre-stage and the stage line.
      The pre-stage beam lights the 1st of the top pair.
      As soon as you break the stage beam, your lane is set, the 2nd lights come on.
      Once the other lane stages, the second pair lights, and (on most ameture nights) you get a half second of each of the 3 single yellows.

      Now, the time starts at the stage beam, but you've already broken it, so time really starts when the beam re-connects. So if you got your tire right on it, soon as you move a c-hair you're timed. The slowest you're moving is the first inch. If you're shallow staged, you have 6 inches of go before you make the beam, so you're already rolling, and already accelerating when your time starts. That 1st yellow light goes, you wanna bring the RPMs just under your stall convertor, say 3000rpms. That 3rd light goes, you floor it, wink your butthole, and take your thumb off the line lock. The dummy lights gonna blind you instantly, so smash the pistol grip & grab 2nd. Hold the F on & stay in it, it'll hook. squeeze the trigger and smash it into 3rd. By the time you light it again, you're done. My pops 454 camaro with 4.10s would hit the shift light right after the quarter mile line, right around 100mph. And those 11 seconds were better than any high, sex, or endorphine I ever felt. And that's "only 11s", and somewhere in there I digress...

      Now, 1/10ths of a second we're talking about here, but if that tenth puts you into the 10s for the first time... well bragging rights are bragging rights.

      deep stage, and you don't have to worry about rollout(your times will be slower, though)

      If his camaro is only doing 100mph, he is only doing high 13s-low 14s. An 11 second car would be doing somewhere closer to 112-120mph.
