I've got five different ways to calculate 1/8 to 1/4 . All five show between high10.20s to high 10.30s . 129-131 mph.

I do too, Wallace is a fabulous resource. But even Wallace can disagree with himself. For example, Wallace 1/8 to 1/4 says op's 6.573 is 10.45, but if you plug in ideal for 106.23, he says it could go 10.teens.
The other methods I use....
Nhra uses ÷.64
Others use x1.57
Can also use x1.58
I also have a chart bookmarked on my phone.
Last is maybe the best, as it is adjustable, if you have a good slip with 1/8 and 1/4 on it. 1/8 + .22= ? Then ÷.655
So...6.573+.22=6.793 6.793÷.655=10.370
If you need to, the.22 constant can be adjusted to work best for your own car. .24 or .25 was accurate for my cars.

The conversion is also affected by what the car/engine is and if NOS or supercharged.

Thought so. Your MPH is 6+ MPH higher than my naturally aspirated with the same 60' & ET in the 1/8th.

Driving takes practice. If you are doing bracket racing... Lots of practice to learn both the starting line and the finish line. If you made a big jump in performance, the comfort should come fairly quickly.

It takes lots of runs down the track to get it right and many more to get CONSISTENT.
