How do oval racing event compensate for lane length?

[RACENUT44]

ON OVALS, THE MOST OF THE TIME YOU ARE RACING THE TRACK, NOT EACH OTHER
AT MAY WAY SPEEDWAY, I ADJUST THE VOLTAGE ON EACH LANE SO THE CAR WILL HAVE THE SAME ET.
THE VOLTAGES RANGE FROM 14V. TO 8V
ALL 6 LANE LANE ARE WITHIN .1 OF EACH OTHER
WE ONLY RACE SPEC CLASSES. SO RACING IS CLOSE
JUST THIS PASS TUESDAY RACES, THE TOP FOUR WAS WITHIN .4 OF ECAH OTHER AFTER 25 LAPS
THREE OR FOUR TIMES A NIGHT, FIRST AND SECOND ARE WITHIN .03 OF EACH OHTER AFTER 25 LAPS
YOU HAVE TO CHANGE THE VOLTAGE FOR EACH CLASS
IT MAKE IT FOR A FUN NIGHT OF RACING EACH OTHER
WE RUN FOR THE FUN
