WR times
BL1:
XFG - 1:32.74
XRG - 1:32.36 (-0.38)
yep, equal
Well for AS22r we'll take the AS2r WR because of the straight
AS2r:
XFG - 1:22.03
XRG - 1:21.40 (-0.63)
SO4:
XFG - 2:03.26
XRG - 2:02.69 (-0.67)
Definately an XFG track yea?
FE25R - We'll take FE2r
FE2r:
XFG - 1:25.68
XRG - 1:24.87 (-0.81)
WE1r:
XFG - 2:09.22
XRG - 2:08.73 (-0.49)
KY2:
XFG - 2:14.12
XRG - 2:13.22 (-0.90)(!!!!!!!!!!)
Its quite clear that 1% likely won't be enough and XRG will walk away with it. Maybe you want 1% for BL1 and MAYBE WE1r and 2 or 3% for the rest. Judging from Turbo Trophy, 3% on the FXO lost it 0.9 seconds at AS2r and 0.45 seconds at BL1r so take from that what you will.
And on the other hand choosing lots of tracks with long straights probably wasn't the best idea.
