Hallo John, I agree with you, that the actual behavior is not what a user expect. Just changing max_vel to "%-Slider" is unfortunately not enough, as also the GUI must be changed to support the new feature.
I from my side can tell that for gmoccapy the amount of work is doable. I will be pleased to do that.

I'd love to hear other opinions.
