No I get it, you’re right.
My point is most every combo I know of runs much closer to the 1.57 factor than it does the 1.56 factor.
Just saying 1.57 is used way more often, no matter what the combo is. And to me is more accurate. Just my opinion.
For instance, Sean Johnson’s car went 5.48 to the 1/8. At 1.57 it’s says 8.60. He ran 8.597.
