Zero Overshoot does not sell “works on all biomedical streams.” Excellence hunt v2 family results for VitalDB SpO2:
| Metric family | Result | Public posture |
|---|---|---|
| Oscillation (SpO2) | 3/6 wins; mean adv −4.3% | Not locked as a win |
| Peak-dev (SpO2) | 3/6; mixed / negative mean | Do not claim universal peak win |
| Contrast: VitalDB HR peaks | 7/7; ~+30.6% peak-dev | Stronger domain cue |
| Contrast: actuator mocks osc | 30/30; ~+32% | Primary industrial story |
Why flat regimes hurt the thermostat story
Soft thermostats shine when there is mid-band energy around a normal. Flat SpO2-like streams often lack that structure; time metrics can favor trackers. Spectral calming may still appear in some packs—do not upgrade that to a product claim without your own validation.
Verdict
Primary public story remains industrial / actuator-class mid-band + peaks. SpO2 is a domain nuance on the homepage for a reason. Validate on your trace class.
