That's stupid. There's no performance advantage in using leaded fuel, which is what was non-compliant. Even using oxygenated fuels wouldn't really be an advantage in supercross - the speed isn't limited by power; it's limited by traction. The AMA is going to screw up the first really competitive supercross championship race in five years.
However, this illustrates the problem with AMA scoring. With 25pts for first and 22pts for second it means that to make up for a DNF you have to win nine races. That's ridiculous. It makes the Championship too much of a crapshoot. It shouldn't take more than three or four wins to compensate for a DNF - or in this case for a penalty that's the same as a DNF.
