First of all, correct there is no way to adjust the clamping force. None is needed.

I'm not saying it's right or wrong but Dyze Design don't have the facility to adjust tension their (expensive) extruders. I queried this on another forum and the maker claims that they have the optimum tension for all scenarios and adjustment isn't necessary.

Applying too little pressure causes the filament to grind before the motor reaches its full potential. However, applying too much pressure causes the motor struggles against friction, inducing filament deformation,

...if the teeth bite deeper into soft filaments so effectively changing the diameter of the hobbed bolt, then wouldn't changing the extrusion multiplier for that filament achieve the same result as adjusting the idler tension?

Does it have to be optimal, or just good enough to work? Not having to adjust tension is pretty appealing, one less thing to forget, one less source of variability. You're right though, the good old test cube isn't a particularly hard test for extruders.Quote

I'm not bought yet, how do we know it is the optimum for each material?

Still, given that it was at least working for that test, and I don't think my extruders would without changing the tension, it is interesting to wonder why there is that difference. One thing about these flex drives is that they use a much greater reduction gearing than a typical extruder, so have more torque available. Perhaps they are running at the high end of the tension range, and while the softer filaments may distort, there's enough torque available to overcome the increased friction. Other differences with my setup are that I'm running 3mm filament and using a nema14 stepper with 5:1 gearing, so I'm definitely running very close to the limits of my available torque.
