As i understand it rollout is how far the car travels with one revolution of the motor.
This is important as it helps to keep the motor in its workable and useable range. This keeps temperatures down prolongs the life of the motor and should keep the power drain on the batteries uniform and not like a thirsty camel.
It also helps with getting the right amount of drive for the track you are at. No point having a zippy point to point car when you have long straights and sweeping turns and vice versa.
To calculate rollout you need to know the tire diameter, pinion gear size and spur gear size plus something else that I cant remember.
check out this site for some more explaining.
