So proud of this car, driver not so much

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.
So, I can speak to this in a couple ways. A lot of factors play into where a car falls onto that 'estimator'. For 1/4mi convertor coupling plays a good part. And who's saying anyone's example is optimized? And at the moment, mine isn't optimized. You can look at SS and stock elims That said, I use these all the time. I like to use them to gage potential so, I like the ones that are optimistic and then target eclipsing them. (That way you know you're doing something)
