Since my detent spring failed I have been able to evaluate the lost motion in the standard cable installation.
There is about 3 clicks worth of lost motion. So, if I pull the mixture control out very slowly with a finger on the panel to allow fine control, I can set the fuel flow to the value I want. To increase the fuel flow slightly I have to push in the equivalent of about 3 clicks before anything changes.
A vernier control with the same amount of lost motion would be useless. I would not consider any vernier control cable unless I knew the lost motion was far less than for the existing cable.
I now have several flights since the detent spring failed and there is no sign of any mixture creep. I prefer the operation without the detent.
