Arithmetic for the Wine Book · Christ’s College, Cambridge
Benedicto benedicatur — now, the reckoning.

New to Nib‑o‑matic? A one‑minute tour
  1. The company first — no names, no dates: the Book knows them already. 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 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.

The company

Members drinking, with neither guests nor presentations anyone with guests or a bottle to present gets a line below — don’t count them here, nor those merely combining
College guests drinking the preacher and suchlike — their share goes to Collegium
A member with guests, or presenting they get their own line — Member A, Member B, … — so their whole entry can be reckoned

Guests drink on their host’s account. Untick “drinking” on a member’s line if they abstain but their guests do not. A mis-tap is undone with ✕.

The wine

One tap per bottle served. Adjust size or price on its line, or say who presented it — give the presenting member a line in the company first, then pick them here. Two bottles from Member A make one combined entry.
