The morning after

Birthday Hangover

He blew out the candles. Did he blow the next game too? Every NHL skater's birthday game and the game after it, measured against his own average.

          The hangover log

          Every birthday game and hangover game this season, newest first.

            How it's measured

            The party is the birthday itself. The birthday game is a game played on the birthday. The hangover game is the player's first game one or two days after it. A player who plays on his birthday and the next night has both.

            Each game is compared with the same player's per-game average in his other games that season, with the birthday and the two days after it left out. Skaters only.

            The verdict pools every hangover game. "Curse" means the points gap is at least two standard errors below zero (roughly 95% sure it isn't luck). Anything inside that is noise.

            Birthdays in May through September have no games, so those players never show up. Feb 29 birthdays are celebrated Feb 28. Nobody actually checked whether anyone partied.
