Further assuming liner acceleration to a terminal speed of 150 mph, that distace equates to about two-tenths of a second.

Kind of like autocross and kart racing--at low speeds, the shorter line wins?

Sorry but that's not how it works, Cars 20 feet apart don't travel an extra 20 feet to become side by side.

Do a simple right angle triangle calculation, over 1/3rd mile you're talking about a tenth of a foot to move over 20 feet.

Also calculating the time delta using linear acceleration will never be remotely accurate.
