Vokkl's AI coach scores every call it hears against four components: Opener strength, Objection handling, Discovery depth, and Value delivery. Each component is scored individually, and the call's overall score is the median of the gradable components, not a simple average. If a category doesn't come up on a given call (for example, no objection was raised), it's marked N/A and excluded from the score rather than counted as a zero. This is designed to give reps specific, actionable feedback rather than one opaque number.
