In the rules it states that 50% of the brake travel can be dedicated to regenerative braking. Does this mean that the first 50% of the brake pedal travel could be partial regenerative braking and then at the 50% point full regeneration is achieved? Or can only 50% of the brake pedal travel be dedicated to any amount of regeneration? In our case, we were considering gradually increasing the amount of regeneration (with a linear potentiometer) as the brake pedal travel increases and reaching maximum regeneration with some brake pedal travel left.

The primary purpose of the rule is to ensure that at *least*
the bottom 50% of the brake pedal travel is directly actuating
the hydraulic brakes.

How you choose to distribute hydraulic and regen is up to
you. Furthermore, the last 50% doesn't have to be hydraulic
only. For example, if you wanted to use a pressure sensor on
the hydraulic circuit and use it to control some portion of the
regen braking, that's OK.
