How to analyse your speedcubing statistics

Averages beat singles

A single solve depends heavily on the scramble; one easy cross can take seconds off. Averages smooth that out, so they're what you watch for progress:

• Ao5 reacts quickly: good for a single session.
• Ao12 is steadier: the best everyday measure of your level.
• Ao100 moves slowly: when it drops, the improvement is real.

Your single PB is worth celebrating, but it says more about a lucky scramble than about your level.

What each number means

The Performance page shows these for your active puzzle and session:

PB (session single)

Your fastest single solve in this session.

Ao5 / Ao12

Your current averages of the last 5 and 12 solves, best and worst dropped.

Best Ao5 / Best Ao12

The lowest Ao5 and Ao12 you've reached in this session.

Ao100

The last 100 solves, five best and five worst dropped: your long-run level.

Mean of 3

The plain average of your last three solves. Any DNF makes it a DNF.

Session mean

The average of every finished solve in the session (DNFs left out).

Worst single

Your slowest finished solve in the session.

Std deviation (σ)

How spread out your times are. Lower means more consistent.

Total solving time

The time spent on finished solves, added up.

Total solves recorded

Every solve in the session, including imported ones.

Which solves count

Every performance number uses solves timed on Cubeathon's own timer. Imported and typed-in times are listed in your history and counted in the solve total, but they never set PBs, averages, mean or σ. Each puzzle and each session has its own numbers.

The trend and distribution charts

• Time trend plots every solve with a rolling Ao12 line. Ignore single spikes; watch whether the Ao12 line slopes down over weeks.
• Distributiongroups your solve times by second. A tall, narrow shape means you're consistent; a long tail of slow solves usually points to one step that sometimes goes wrong, such as a missed F2L pair or a last-layer case you don't know.

Reading σ

Standard deviation is easiest to use as a comparison with yourself: if your mean drops but σ rises, you're faster on good solves but making more mistakes. Lower σ at the same mean is progress too.

Session trend and comparison

The timer's drawer has a Statstab for the session you're in:

• Session trend — from three timed solves, a chart of the session and a line comparing your first five solves with your last five.
• Compare sessions — pick another session on the same puzzle and see Best Ao5, Best Ao12, PB and mean side by side, with the change.
• Personal best journey — each time your PB improved, and by how much.

Comparing sessions is the clearest way to test a change: put a week of solves with a new method or cube in a new session, then compare it with the old one. See tracking solves and sessions.

The Coach tab

After five solves, the drawer's Coach tab looks at your recent solves and, when something stands out, says what it sees, why it matters and one thing to focus on. It watches for:

• several DNFs in a session;
• a plateau, where your last three blocks of solves average almost the same;
• times swinging more than usual;
• a session clearly faster than your previous block;
• unusually consistent times.

If nothing stands out, it stays quiet rather than inventing advice.

A weekly review

1. Check your Ao12 and Ao100 on the Performance page, and the slope of the trend line.
2. Look at the distribution for a tail of slow solves, then find out which step causes them.
3. Practise that step: F2L, OLL or PLL.
4. Glance at your dashboard: its training calendar and streak show how regularly you actually practised.
