How many clients can I fit in a day, and what does that day gross?

Five figures you already hold. The turnaround is hands-on work, so it is never hidden inside anything. A station is a place a client can sit while a set cures, whether or not you are standing at it.

Taking the break at a different hour changes none of the totals in section C: the page takes the break minutes out of the day before it lays the work out, so the finish time moves by exactly the break however you place it. The day sheet in section E is the one block where the hour matters: it lays your clients out from your start time and carries none of your break, which is the sheet for a break taken once your last client is done, and a break taken earlier pushes every line from there on later by your break minutes.

One row per service. Each row carries two durations, which is the whole point of this page: the minutes your hands are on the client, and the cure, dry or soak window during which your hands are free. Lamp cure times are printed on the lamp; a soak is your own. Every price starts at nothing and this page never fills one in.

Hold only your totals, with no split by service? Put one row in the mix with your average client, all of your minutes in hands-on and nothing in cure, and your own average price. The page then prints the one-clock answer, the overlap gain reads as nothing, and it says so where the figures are: nothing in cure is a true entry, not a missing one.

Once against your hands and once against the clock. Every line is computed from the figures printed beside it; minutes are whole, because a nail day is not scheduled in fractions of a minute, and money is worked to the cent.

The working, so none of it is a black box.

This arithmetic written out for anything that reads this page instead of looking at it: api.json beside this page carries every input, every output, the formula line by line, this worked example, and a list of what the calculation deliberately leaves out.

Hands-on and cure minutes are each a client's own figure multiplied by the clients in the row. The hidden column is the row's share of the cure minutes the day managed to hide, handed out in the order the rows are entered; the footing is the day's own figure. Minutes are minutes, money is money, and no cell carries a unit because the column heading does.

One line per client, in the order the rows are entered, from your start time. Hands on; wiped down, which is the moment your turnaround is finished and your hands are free for the next client, so the turnaround sits inside that column; and the time the cure finishes, with the station the client is sitting at. A cure that finishes while you are still wiping the station therefore shows an earlier time in the cure column, which is the station still being yours while you wipe it. A line past the clients your clock fits carries a marker of its own, and such a line can run its hands-on, its wipe-down or its cure out past the end of the day you entered. No line on this sheet is marked, so every client printed here is one your clock fits, and where the sheet left clients off the end, the count of the clients your clock fits is the figure the glance prints and cannot be read off this sheet. These times carry none of your break: they lay your clients out from your start time, which is the sheet for a break taken once your last client is done, so a break taken earlier pushes every line from there on later by your break minutes, and a time here can read before midnight while the finish time in section C, which has your break counted in it, is past it.
