How ChasePulse Works
Advanced probability models powered by verified sighting data
Model A: Deterministic
Simple count of verified sightings subtracted from the print run. Shows the minimum number of cards still unseen.
Model B: Bayesian
Statistical estimation accounting for cards that may never surface publicly. Provides probability that copies remain in sealed product.
Verified Data
All sightings are reviewed before affecting probabilities. Sources include YouTube breaks, eBay listings, and PSA registry.
