🕯 Nib‑o‑matic 🍷

1. The company first — nothing to type: members are lettered automatically and the reckoning works out the date itself (last evening’s, in the small hours). Count the drinking members with neither guests nor presentations on the first stepper, and any College guests (the preacher and suchlike) on the second, bound for Collegium. A member who brought guests, or who presented a bottle, gets their own line — tap the + beside “A member with guests, or presenting”, and they become Member A, Member B, and so on.
2. Then the wine — tap a chip once for each bottle put out (twice for two of claret). Each tap adds a line where you can adjust the size or price, or say who presented it — Member A, Member B, or the College. Presented bottles stay out of the division, and each member’s entry comes out with shares and bottles already added together, however many they presented.
3. The reckoning — updates with every tap; nothing to submit, and nothing left to add up. Every entry is a final figure to copy into the Book by hand: the date and bottle count for the head of the column, the share against each member, each named member’s total with presentations folded in, Collegium, Gains, and the audit line to satisfy posterity.

You know the rules; this merely does the sums. Rounding up, Gains, Collegium, and X marks are handled automatically — and if the numbers cannot be right, it will say so. Should the phone wander off mid-reckoning, the evening is picked up where you left off, and holds until noon the morning after.

Set these once from the price sheet in the Book; the chips, and any bottle line you haven’t priced by hand, will follow.
