No idea why... and it's an epic blast from the past, but was thinking about this the other day (more thinking that the numbers didn't add up and if I was nearly hitting 1g accelerating that I should have crossed the line much quicker than 15.8 @ 86mph )

Doing 64ft in 2 seconds surely can't be 1g, as gravity is 32ish ft per second per second.

Soooo, the first second, you have to cover 32 ft. In the second (2nd) second, you have to cover 64 ft (as speed is increasing 32ft per second, add another 32ft onto the first second), so total distance is 96ft in 2 secs to acheive 1g. Extrapolating back that'd give you... something like 1.6 seconds for a 1g average 64ft?

Or have I missed something?
