How it works

A fixed $30,000 budget is split four ways by the sliders. Each guest-facing category converts spend-per-guest into a quality score with diminishing returns (extra dollars help less once a station is already good):

quality_i = 100 · clamp( sqrt( (budget·w_i) / (guests·refCost_i) ), 0, 1.3 )

Staff & logistics spend does not add its own "quality" — instead it sets a flow factor that raises every station's serving capacity and speeds up how fast guests move through the venue:

flow = clamp(0.6 + staffQuality/100, 0.6, 1.8)
capacity_i = baseCapacity_i · flow
dwell_i    = baseDwell / flow · max(1, occupancy_i / capacity_i)

Each guest agent visits Catering, Entertainment and Décor in an order set by the event-type preference weights, and leaves each station with a satisfaction contribution equal to that station's quality — discounted if it was over capacity when they arrived (a proxy for queueing and wait time). A guest's final satisfaction is the preference-weighted average across all three stops; the panel's overall figure is the running average over every guest who has finished their visit.

Budget sliders — reallocate spend live; station heights and guest colors update immediately.
Guest count — more guests share the same fixed budget, so per-guest spend (and quality) falls unless staffing absorbs the extra flow.
Trigger vendor delay — knocks catering quality and capacity down for 8 seconds, modelling a late supplier, so you can see a logistics shock ripple into the satisfaction score.
