Field notes
The page describes four nightly checks: search terms missing from titles, blank eBay item specifics, prices compared with current listings for an exact card match, and watcher count relative to listing age and price. One sample price flag compares three current listings and reports a median-relative gap; another pairs one watcher with 240 days listed. The maker says the checks were tuned on the rorzcards store.
