Why is establishing quantifiable performance targets crucial early in development?

Answer

It allows engineers to tune control algorithms against a specific, measurable benchmark rather than a subjective feeling.

Vague aims like 'less fatigue' are insufficient; engineers need actionable targets, such as a specific $ ext{Torque}_{ ext{Assisted}} / ext{Torque}_{ ext{Required}}$ ratio, to iteratively test and tune control algorithms.
