Four-camera Perseid records have fewer formal unbound flags than two-camera records in GMN 2023 and 2024
We compare formal solar-unbound flags by camera count in frozen GMN Perseid records. After quality cuts, two-camera records have flag fractions of 5.134% in 2023 and 5.627% in 2024. Four-or-more-camera records have fractions of 0.659% and 0.775%. The fraction ratios are 0.128 and 0.138. Peak-season cuts, stricter track cuts and a check for repeated solutions retain the ordering. We use a date-dependent solar escape boundary and a threshold of five quoted speed errors. The result is a catalog association. Brightness, coverage, geometry, shower assignment and shared errors can affect it. It does not measure the causal benefit of more cameras, calibrate error probabilities or confirm an interstellar meteor. Both years use one network. Independent instrument confirmation is absent. Code, compact attributed inputs, source hashes, tables and a static figure support offline reproduction.
