16% with an 8.5mm seems to give better lap times than 7mm 25% for about the same mileage.
My thinking is the same way. I'm running large venturi's and 20% nitro with awesome power and fuel mileage. Truggy I'm running a 9mm insert in my speed and getting between 12 and 14 minutes on a tank. Buggy I'm running an 8 and getting between 9 and 12 minutes on a tank. The larger inserts provide a smoother powerband as well.
