At what switching penalty does a proportional infrared gate beat the on/off thermostat gate?

What it found

A stylised, preliminary follow-up to garment-twonodeprop. Both gates are retuned on training rooms for each actuation lag and a per-swing penalty (one full close-to-open swing = 1 for either gate; the penalty scale is an assumption), then scored on held-out rooms. The proportional gate has the lower cost in 52 of 80 cells, by at most 0.096 C on a proxy of order 0.3–1.5 C; at the highest penalty the gain holds in the between rooms (8 of 8) but mostly reverses in the outside rooms (2 of 8). Simulated comfort, not a claim about any real garment.

• Is the outside-room reversal of the proportional infrared gate a training-range artefact?Retunes both infrared gates on a wider set of rooms: the proportional gate's outside-room reversal is partly a training-range artefact
• Does an infrared-gating band tuned for one person and clothing level still work for other clothing and body sizes?Tunes both infrared gates on one person and clothing level and scores them on other clothing and body sizes; clothing matters, body size barely does
• How far is the thermostat-driven infrared-gating textile from the best possible switching schedule when the room temperature steps?A grid search for the best open/closed switching schedule under a room-temperature step shows one toggle suffices and the thermostat gate sits within 0.02 °C of it after a step up, but up to 0.11 °C after a step down (stylised).
• What does a degree of comfort cost in fabric?Joins garment-thermal comfort shifts to garment-teardown costs: only one fabric treatment helps in each scenario, levers combine sub-additively, and at assumed premiums a degree costs $0.5 to $19 on a replica trench but $3 to $114 on a designer one. Stylised; premiums assumed.
• Does a fabric lever still pay once you weight it by where the garment is worn?Weights garment-comfortcost's fabric levers by wearing time and adds a gated infrared lever: a fixed infrared-transparent shell pays only with a warm-room majority (above 75.5% of time against the cool room), white never harms, and the gate is chosen only when it costs about the fixed shell's premium or less. Stylised; premiums and wearing shares assumed.
• How many home-sewn coats before the labour cost per coat settles?How many home-sewn replica coats until labour cost settles? On a Wright learning curve (assumed first coat 4× an experienced operator, rate 0.85) it takes 20 coats to get within 2× of factory time; the first coat stays under $50 only if your time is valued at ≤$1.45/h. Learning parameters assumed. Stylised.
