You want to stick with 1 fuel grade till you learn the spread from each fuel on jetting.I did a couple 60' launches in my drive and read my plugs till I move on to the next step of jetting.[add pv]I have #7 plugs in.

I wouldn't put much stock on doing what you did in the driveway with the accelerator circuit furnishing a lot of added fuel to the launches work twocents
I would go drive it at light part throttle now to see what it is running like on the idle and transition circuits and go from there scope twocents
I would use a G meter or the sixty foot times at the track to tune the accelerator circuits, not the spark plug looks up
I agree and I want to see what his look like with newer plugs side by side when he does.
