The 99 is more reliable, but at the national level parity IS an issue at the pointy end of the field.  The 99 is fastest when on the edge, but one jet to lean an things dont break, it just slows down .

 

The 01s are VERY consistent from cylinder to cylinder… but if they are too lean, they break parts.  And they run best while they are on the verge of breaking.

 

I think this is an easy fix.  Raise the octane of the fuel so instead of detonation the motor slows down when its too lean.  it still needs to be jetted right to win, but instead of breaking parts it just slows down.
