Why not just make a informal pact- use DPN uni rating when racing open class (Tback and I talked about this) and elapsed time when in a f16 class. but then what about mixed blades racing in open class??? Who is going to be racing 2-up and uni at Juanas? I wouldn't mind just doing it that way and know that amongst the blades first over the line wins (among the f16s) regardless of the numbers game.
