How it works
Add up all the game totals and divide by the number of games. The average is shown to one decimal place.
A few games can give a shaky average, because one strong or weak night moves it a lot. More games make the number steadier.
Worked example
Across 5 games with 913 pins in all, the average is 182.6.
Questions
How do I add a game?
Add its total to the list. Each number is one game's total score, not the score of a single frame.
Why does the average move so much early on?
With few games, one high or low game shifts the mean a lot. It settles as more games are added.
Does handicap change the average?
No. This works from the raw game totals. A league handicap is a separate figure that the league works out.
