Understanding Your Average: What It Really Tells You About Your Game
Your three-dart average is the single most talked-about number in darts. It sits at the heart of every commentary, every post-match analysis, and every honest conversation about whether your game is improving.
But most players use it without fully understanding what it measures, or what it doesn't.
This guide explains what your average actually tells you, how to track it properly, and where it fits into a broader picture of player development.
What is a three-dart average?
A three-dart average is calculated by dividing the total score thrown by the number of visits (sets of three darts), giving an average score per visit.
In 501, averages are also commonly expressed as a per-dart figure, simply the three-dart average divided by three. You will see this in televised coverage, where commentators reference a "100 average" meaning 100 per three darts, or roughly 33 per single dart.
A 501 leg finished in 15 darts (five visits) with a total score of 501 gives an average of 100.2. That is a very strong performance.
For context:
- Below 40: beginner, developing mechanics
- 40 to 60: regular social player
- 60 to 80: consistent club level
- 80 to 100: competitive amateur and strong league player
- 100 and above: tour card and professional territory
What your average actually measures
Your average is a composite number. It combines three separate skills into a single figure.
Scoring consistency. How reliably you score on your visits. Players who hit the treble 20 consistently (or score on T19, T18, or other efficient segments) will carry a higher average than those who scatter.
Checkout ability. Unfinished legs pull your average down significantly. A player who leaves a game on the double for three additional darts is losing not just time, they are losing average.
Tactical awareness. Knowing when to switch to a more accessible target, when to set up a clean leave, and when to press for the big finish. Poor tactical decisions cost scoring visits.
Most players who feel like they have hit a ceiling are losing ground in one of these three areas, not all three.
Why the average can mislead you
A high average in a single session does not always reflect what you think it does.
Averages go up when you face good checkouts that fall in two darts. They go down when you leave awkward numbers that cost an extra visit. Format, opponent, and even leg length affect the number.
Two players with the same average can be at very different stages of development. One might be scoring brilliantly but leaking legs on the double. The other might be finishing efficiently from limited scoring. Same number, very different games.
This is why tracking your average in isolation is less useful than tracking it alongside:
- Checkout percentage (legs finished as a proportion of checkout opportunities)
- First-nine average (a cleaner read of raw scoring pace)
- Treble hit rate (how reliably you are hitting your intended target)
How to track it properly
A session average calculated from a handful of legs is not particularly meaningful. Variance in darts is high. You need a larger sample.
Aim to track your average across:
- A minimum of 10 legs per session
- Rolling 7-day and 30-day windows
- A consistent format (always 501 straight-start double-out, for example)
This gives you genuine trend data rather than a snapshot that reflects whether you happened to land a 170 on your second visit. A simple notebook, a spreadsheet, or a scoring app all work. What matters is recording the same way every time, so the numbers stay comparable.
The number is a tool, not a verdict
Your average tells you where your game is performing. It does not tell you why, or what to do next.
Use it to identify trends. Use it to spot where a session went well or came apart. But do not let a single number define your sense of progress. Darts development is less linear than the average suggests.
A player who drops three points on their average while cleaning up their checkout percentage is almost certainly improving. The number just has not caught up yet.
