The scale was made mainly for L1/L2/R0/R1/R2 multi axis scripts since they will always hover around 50%.
If the scripter assumes large physical range, like +/- 45 degrees for pitch/roll while the device can only do like +/- 20, the script will be very flat and the scale can help boost those type of scripts.
It does not really work that well for stroke scripts, unless they are centered around 50% which would be rare.
Scale definitely should not be used for adjusting range, use output range sliders for that.
I already have a rework of scaling planned so there will be more usable scaling methods for stroke axis in the future.
If you have suggestions on how the scaling should work please let me know.
