"Bigger windows buy you room, not comprehension." That's the line I'll keep. We learned it the expensive way.

Thanks, Salman! Glad that line stuck with you. I'd love to hear what the expensive lesson was for your team, since those stories are usually the most useful ones for other readers.

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?
