yellow (thin sample) — large gap but N < 30 (more samples needed)
What has to hold before NBA EV goes live (all three):
N ≥ 200 settled NBA picks
Model Brier ≤ market Brier + 0.005 (the model no worse than the market beyond noise)
Zero red buckets across the 0.50–0.95 probability range
Calibration uses every settled NBA pick. Model Brier scores the
model's probability against the result; market Brier scores the no-vig
market price on the same picks.
