Measure each partner's on-the-ball work (surgeries, triage, home visits, patients) and their off-the-ball work (clinical-lead role, GP training/supervision, meetings, admin/bloods/tasks) — pro-rata across different session counts — so the invisible load is seen and the split is fair. It also flags the low-value, automatable time worth reclaiming. Edit the example partners or add your own; everything recalculates live.
