Thanks Rich, I stand corrected. I didn't realise the brakes were also based on a profile like the throttle.
In my defence I was reading the supplementary manual, whose explanation is not as expansive as the original user guide where it clearly states: "...allows you to set a certain level of 'hand-brake effect', i.e. you can vary the minimum brake effect when you apply the brake."
Next time I'll read the manual in full
