The floor

Build the room, set the hours, write one offer, type the money, then launch. It all happens in this tab, and nothing you type is sent anywhere.

Every arrival, station count and open-block length here was typed by whoever built this sheet. Praxium supplies no demand, no attendance and no example sheet to measure it against.

Each entry carries the sentence that qualifies it at the field, the chart or the banner where it is used. The method, both coefficient ledgers and the list of things this cannot tell you are on the Studio Sim explainer.

Start with a studio that already runs

Every one of these is invented, top to bottom, so it can be scored and so it can be broken. Pick one and it loads complete: floor, hours, menu, offer, money, and the rule of the fiction it is scored against.

  • Thin cash, quiet winter

    A small annex room with a short menu, a membership that roughly covers the rent, and a bank balance that would not survive a bad quarter. Members are leaving a little faster than they arrive, so revenue drifts down while every fixed cost stays exactly where it is.

    Which lever do you pull while there is still cash to pull it with: the price, the cost line, or the rate people arrive at?

    This scenario's win line: finish the horizon with the bank above where it started and the membership no smaller than it began.

  • The evening crush

    A full boutique floor with one sauna and one contrast suite, and a membership that almost all wants the room after work. Mornings sit nearly empty while the evening queue runs past the end of the block, and both protocols on the menu pass through the same two single stations.

    Nobody is going to sell you a second sauna in this scenario, so can the demand itself be moved off the peak, or the menu rebalanced so fewer visits arrive at the station that binds?

    This scenario's win line: bring the evening wait band down and keep the membership whole while doing it.

  • The sauna with a payment attached

    A room built around a single sauna that both protocols walk through, a membership that is growing, and enough in the bank to consider buying the way out. The scenario's finance rule turns unserved visits into members lost, so the queue is not free to leave alone.

    Capacity here has a price and a payment schedule. Do you buy early and carry the dip, buy late and carry the queue, or decide the room is fine as it is?

    This scenario's win line: end the horizon with more members than you started with, and with the bank never dropping through the floor the scenario sets.

  • The leaky cohort

    Two memberships on a busy floor, plenty of people arriving every month, and a back door nobody has closed. The lighter membership leaves fastest, the heavier one walks the longest protocol, and the scenario's own rule says a queue past a certain length costs members.

    Growth here is already paid for, so the question is what keeps it: a change to what the memberships include, a change to the mix of protocols they run, or a stated belief about what a shorter wait is worth?

    This scenario's win line: both memberships end the horizon larger than they started, without the wait band widening to get there.

  • Two doors, one room

    A large floor running a heavy protocol built around its single float tank and a light protocol that barely touches the busy stations. The premium membership is small and walks the heavy one; the wider membership is large and mostly walks the light one, and the two want completely different things from the same building.

    Both doors are open and only one of them scales in this room. Which membership do you grow, and what do you change about what each one runs?

    This scenario's win line: end the horizon with the floor's scarce stations carrying visits that the memberships paying for them actually asked for.

  • The house that refuses

    A modest room that opens four days a week and closes early, running under the enrollment cap rather than the queue: when the projected visits outrun what the floor can serve, the scenario refuses the intake instead of letting a wait build. People keep arriving at the door and the model keeps turning them away.

    The refusals are the scenario telling you the room is shut, not that the demand is wrong. Do you open the building further, move the demand into the hours that already exist, or change the policy and accept the queue that comes with it?

    This scenario's win line: end the horizon with the refusals gone and the membership larger, without the room running past what it can serve.

Or model the studio you actually run

Nineteen entries stand between an empty page and a month on screen. Every one of them is a number only you have. Nothing is filled in for you, and a field left empty stays empty rather than becoming a zero.
