If the lanes are 1 meter wide and the straights are 40 meters long, that's a mere 1 centimeter extra he would have run by drifting to lane two - or .0014 seconds. When you factor in the energy he saved by not trying to counteract centrifugal force it was probably a wash. Also totally insignificant compared to the time saved by drafting and hugging the curb on the corners.
Can we see your formula? That doesn't seem right to me.
Isn't it like 3 meters per lap versus lane 1 or lane 2. How could it be only 1 cm?
sqrt(40m^2 + 1m^2) - 40m = ~0.0125m
40m = roughly the straightaway length, 1m = roughly the lane width
