This may not map to other packs/troops, or bear out statistically, but at our last bridging ceremony for Webelos we found that the Cub leaders had been busier in terms of administering first aid: one case anaphylaxis, one concussion, one dislocation from a cub who took a tumble running down a hill, and one bad encounter with a likely peanut allergy. All required trips to the ER. Pin a medal on any adult who took on all that!
