Abstract
This paper provides a comparison of the air change rates measured by perfluorocarbone tracergas (PFT) and SF6 tracer gas decay, and the house airtightness measured by a blower doorduring the winter season of 2008-09 in 68 homes in Québec City, Canada. The average airchange rates for all the homes were similar for SF6 and PFT, however the individualmeasurements did not correlate well. A better inverse correlation was obtained betweenmeasured formaldehyde concentrations and the air change rates based on PFT measurementsthan those based on SF6 measurements. Using on the PFT measurements, 83% of the homesdid not achieve the nominal guideline of 0.35 air changes per hour for residential buildings.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
