Rick I would love to say yes, but I just don't see how it's possible as you are really compairing apples and oranges by trying to compare 1 seat vs 2 seat. No doubt it is easier to score well in 1 seat so how do you wieght the judging to account for that? Further more is it even possible to fairly weight 1 seat to even out the playing field, and by doing so don't you risk people choosing to claim 2 seat so that they can have lax judging and then focus solely on the 1 seat style of tuning and hope the passenger seat doesn't drag them to far?
that is only the tip of mountain of issues you could face by combining the two. . .
