I am puzzled by your statement that the Walker "holds speed over a longer period of time". Does the actual output frequency of the VPI unit drift over time?
I can see no other mechanism causing the effect you have observed
The major determinants of speed stability with belt TTs are mechanical and are therefore independent of the setting of the controller.
