About the clutch, and where it 'bites'. That is really a function of the applied torque. Think of the clutch as a brake system. If there's little torque applied, the biting point will be further in, because the pedal really control how much torque the clutch can transfer. That also sort of confirm Cue-Ball's observation about the first 1" of depression not really doing anything. Well, it does. You are reducing the POTENTIAL torque transfer, or preload, but the engine is not putting out enough torque for the clutch to start slipping. And that's where I think Scawen might have got it wrong. There is just not enough preload in the clutch.
Let's analyze:
Assume the clutch is linear in operation, and the max torque it can transfer without slipping is 300Nm. The engine we are using can supply 200Nm. So the clutch would be fully engaged at 2/3 travel, correct?
There's also the element of static and dynamic friction, which might be part of the issue here, the transition from dynamic to static which in most cars will feel like a 'jolt'.
The static friction is higher than the dynamic friction, so maybe Scawen took the staticv friction number when calculating the max torque the clutch can hold when matching the clutch to the engine, and forgot about the lower dynamic friction? Just throwing out ideas here...
Personally I think the clutches need to be 'stiffer' (more preload) so they lock properly when fully lifted.
