Obviously I don't need each run analyzed - just figured I'd share all the data I have available.

Thank you!

2 runs: https://datazap.me/u/mfish123/55-deg...e-14-mile-runs
3 runs: https://datazap.me/u/mfish123/55-deg...3-14-mile-runs
Some good data there, useful for the community! Results are shown below and I think it speaks for itself. Acceleration is in arbitrary units (but all relative). As can be seen, 1st gear shows highest acceleration up to approx. 6000rpm. It tapers quite strong at 6500rpm. Black arrow show shift RPM to maintain highest acceleration.
It appears a shift point of 6100 rpm suits well for at least the first 4 gears.
