OK then, so why constrain the bars in the comparison bikes to be an obviously slower 3:1 configuration? If you want to claim you're fastest Tri bike, then put the Ventus back on the P4 and then make the comparison.
To accommodate your desire to compare the bikes in an "as purchased" condition, then you'd probably want to follow Steve Harad's (Kestrel) idea of testing protocols...
Plus...you don't think that they tested the final configuration of the SC in "UCI-legal" trim? I'd be shocked if they didn't ;-)
