Example — season 2026, all amounts in USD.
| Access | Total cost | Rod-days | Cost per rod-day |
|---|---|---|---|
| Access X | 5,300 | 7 | 757.14 |
| Access Y | 5,000 | 0 | Not computable |
Cost per rod-day — total cost divided by rod-days from Access Activity. An unused access shows “not computable” — its cost stays visible, it never divides by zero.
During the season this view reads “projection — season to date”.
How to verify it: Using the owner-payables seed, Access X totals USD 5,300 (200 accrued + 100 paid at access + 5,000 season charge) over 7 rod-days — the report must show USD 757.14 per rod-day, while unused Access Y keeps its USD 5,000 cost with a “not computable” rate.
