Record each scratch game before adding handicap or team points. Your own sheet should let you recover the series total and running average without guessing which numbers already include an adjustment.
Three-game example
| Game | Scratch score | Running series |
|---|---|---|
| 1 | 154 | 154 |
| 2 | 166 | 320 |
| 3 | 160 | 480 |
The series average is 480 ÷ 3 = 160. Write the date, league, and bowler beside the games. If you also track lane assignment or ball changes, keep those notes separate from the score columns.
For a second three-game series of 170, 155, and 165, the series total is 490. Across all six games, the total is 970 and the average is 970 ÷ 6 = 161.67, before applying whatever rounding rule your league uses.
Weight averages by games
If one session has two games and another has three, don’t average the two session averages directly. Add all scratch pins and divide by all games. Equal weighting only works when the game counts are equal.
Keep these season columns:
- Date and accepted scratch games.
- Series total.
- Season scratch total.
- Season games played.
- Calculated average and the league’s accepted average, if different.
Handicap and team points
Put handicap in its own column and label whether it applies per game or per series. Use your league’s published basis, percentage, limits, and rounding method. There is no single handicap formula this sheet can safely assume for every league.
Team match points belong in another column. A high scratch series and a team match win describe different results.
Corrections
Keep the original accepted score until you can compare it with the league report. When a correction is approved, update the affected series and season totals together. Record the date of the change so a later discrepancy has an explanation.
This is a personal tracking sheet. The league’s accepted records govern its standings and averages.
