Reference · your own numbers
The engine is generic. Your florist is not.
Every figure this application produces is derived the same way for everybody, which is the point — it is reproducible, and you can read the rule. It is also, for any given studio, wrong in a consistent direction. This florist runs over on stems. Load-in at a historic house always takes an hour longer than anybody declares. Recording an actual is opt-in and off until you type one. Nothing on this page changes a figure.
After an evening you can record what actually happened beside what was derived. This is where those add up. It is not telemetry — nothing is observed, every reading exists because a person typed it — and nothing here is applied to a figure. What it produces is a sentence to argue with.
