Before Golden Lever, Fighting Games joysticks are treated as toy and there are not much development to improve it, everyone forced to use it as it is.
When we developing Golden Lever ecosystem, we want to let everyone to be able to setup their own lever according to their play style and preferences.
To be able to tune lever more precisely, we need better data than just subjective measurement. We develop a tool that be able to measure three main properties from a lever "Tension, Sensitivity, and Throw".
The idea is simple, we build a Rig with linear motion that can be measured, and put a Force Gauge that will measure the force while we push the lever.
