That 40 out of 500 number sounds about right from my own folders, so the real question is what that one prompt style was doing that the others were not. Was it a specific subject, a lighting setup, or just the wording you kept tweaking until the model settled into a groove? I keep landing on the same handful of phrases too, and I am starting to wonder if the prompt matters more than the checkpoint.

My uncle had a moisture meter that beeped so much we thought it was a Geiger counter, kept telling him his whole basement was radioactive. Turns out the batteries were dying and it was just making noise. He still swears by the old-school way though, feels the wood like he's reading tea leaves.

Those 2 days of ringing stopped being worth it once I realized the highs come back but the crowd noise drowns out the mix anyway.
