Tennis Match Statistics: Serve & Return Points, Break Points, Point-Win Probabilities, Game & Set Win Chances and Match Reports

What you'll build

What you will be able to do

Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.

• Read a fictional point-by-point log, build a game key for every point, mark whether the server won it and work out one player's share of the points and the average rally length of the points she won.
• Turn 24 logged service points into the four classic serve numbers for both players: first serve in %, points won on the first serve, points won on the second serve and double faults.
• Measure Nell's return game over six fictional club matches: return points won, all points won, the season's break rate and the dominance ratio that weighs return against serve.
• Work out break points saved and converted per match and for the season, combine them into a pressure-points share and compare it with the share of all points won.
• Turn a server's point-win chance p into the chance of holding serve: winning before deuce, reaching deuce, winning from deuce and the total – and see how a small edge per point grows per game.
• Look up a set win chance for every player from a fictional table, turn it into a best-of-three match chance, find the point share a target needs and measure how much a small point edge grows over a match.
• Sort 20 points into rally-length bands with a lookup, count the points per band, find where Nell wins most and compare her winners with her own unforced errors.
• Finish Nell's season report: points won % per match, the pooled season share, the trend of her first-serve percentage and a line chart for the club noticeboard.
