Hello Hafiack,
I can show you my settings.
The Multiplier was measured with a Laser RPM Meter.
But unfortunately it works just with one gear with my settings.
When i use another Gear with the respective the Spindle Pulley settings, i have to re adjust the Multiplier.
So for the most cases my Servo has enough power in this 6 Gear.
But maybe there is just an another option to use more Pulleys without adjust the Multiplier.
