How This Works:

We use an exponential curve starting from half your 1st gear speed. The curve steepness control lets you adjust how aggressive the progression is - lower values create very steep curves with large gaps in lower gears, while higher values create more linear progressions.

Green values: Your calculated optimal gear speeds
Gap: Speed difference to the next gear
Curve Factor: Controls steepness (0.1 = very steep, 1.0 = linear)
