Gday. Same discussion here while back. See if can find. Believe the extra distance covered per lap the same at any track. Something to do with radius of a circle. Can cover more ground at different tracks but only because might go round more bends. So 2000m race round 3 bends cover more ground than 2000m round 2 bends.

Also if 7m extra 1 off fence them 14m extra 3 off fence 21m 4 off....
See if can find.
