Hit. See. Fix. Next.

The first reps establish a baseline. The rest show what repeats, what drifts, and whether one change actually helped.

See the pattern. Carry the context.

Representative beta screens show how one session can surface a repeated pattern, save the cue and result, and inform a rolling benchmark with one next priority. Views span a session and longer-term history; example data shown.

  1. Start

    Set the baseline.

    Begin with normal swings. ARC waits for a pattern before suggesting a change.

  2. Pattern

    See what repeats.

    The summary keeps the best rep, costly miss, and useful streak in one view.

  3. Test

    Try one cue.

    Change one thing and watch whether contact, start line, or tempo moves with it.

  4. Save

    Carry it forward.

    Keep the cue and result so the next session starts with context.
