Model rankings move weekly so I stop chasing the chart and lock a default for a sprint. The win is a stable loop with clear failure modes not a new top score every Monday.
Locking a default for a sprint is a smart way to work, Brian. A model you know well, with failure modes you've already mapped, beats a slightly higher benchmark score you haven't tested yet. Do you keep a short list of the failure cases you watch for, or do you find them as you go?
