Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the station rotation time docket: your section | groups in sequence | minutes per group stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: The multiplier is groups per lane, not station count when stations work in parallel. After: the station rotation time docket shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Optional AI formatting, not calculation
For this station rotation time docket, an external AI text tool may help format non-sensitive notes if you already use one. No AI service or account is required: manual entry completes the same free core calculation. Do not paste private or sensitive data. Review every value against the source before using it.
Format my non-sensitive notes for a station rotation time docket. Return plain rows only: section | groups in sequence | minutes per group. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: section | groups in sequence | minutes per group. No AI response is executed as code.
