Two telescope samples give no clear positive fluence link to the next detected wait for FRB 20220912A
We test whether brighter burst groups precede longer detected waits in FRB 20220912A. We fit log wait against log fluence with separate session intercepts. CHIME Catalog 2 gives slope 0.053, with a nominal 95 percent session-bootstrap interval from -0.352 to 0.348, in 74 pairs from 18 sessions. A separate Nancay telescope table gives slope -0.011, with interval -0.111 to 0.078, in 556 pairs from 29 sessions. Time trends, wait cuts, close-event grouping, and time splits give no clear positive relation. A strong-signal CHIME control has insufficient data. The result tests waits of 5 to 1800 seconds under stated selection rules. It does not exclude energy storage models: measured fluence need not trace total energy, and bursts can be missed. No new source or physical event is claimed. Code, selected source rows, hashes, controls and offline steps are included.
