How scoring works

Every round is judged on one thing: how close you land. No partial credit for effort, no fixed pass-or-fail margin.

Precision, 0 to 100

Each round gives a precision score from 0 to 100, based on how close your answer is to the target relative to the round. Land it and you score near 100; the further off, the lower it falls.

The rule is deliberately simple, and it accounts for every score you are realistically going to see:

Your precision is 100 minus your error as a percentage of the target. Miss a 4-second target by 0.20 seconds and that's a 5 per cent error, so you score 95. Miss it by 0.40 and you score 90.

The same miss isn't always the same score

Because error is measured against the target, an identical miss is worth different amounts in different rounds:

0.20 seconds off a 2-second target is a 10 per cent error, worth 90 points.
0.20 seconds off a 4-second target is 5 per cent, worth 95 points.
0.20 seconds off a 10-second target is 2 per cent, worth 98 points.

That isn't an arbitrary handicap. Human timing error grows in proportion to the interval being timed, which is one of the most reliable findings in the field, so holding you to a fixed margin at every length would mean quietly scoring the long rounds much harder than the short ones. Why timing error scales with duration goes into the research behind it.

Double and half are equally wrong

Error is measured in proportion, and proportion runs in both directions. Answering 8 seconds on a 4-second target and answering 2 seconds on it are the same mistake mirrored, so they score the same, about 31. Marking the raw difference against the target would call the first one twice as bad as the second, and would flatten everything beyond double the target into the same 0, which tells you nothing about how far out you really were.

You reach 0 once you are wrong by a factor of about 2.7 either way: answering 11 seconds, or 1.5 seconds, to a 4-second target.

Points per round

Your precision becomes the round's points. A full 100 is reserved for a literal, dead-on hit, so anything short of perfect caps at 99. When you see a 100, it means exact.

Result tiers

Each round's square (the ones in your shared result) comes from its points:

⭐Exact: a literal, dead-on 100
🟩Sharp: 90 and up
🟨Close: 80 to 89
🟧Off: 65 to 79
🟥Way off: below 65

How Tempo is different

Four of the five modes score a single moment: one answer against one target. Tempo scores a sequence, judging each gap you produce against the reference beat, so what it rewards is steadiness. Sitting a fraction slow but perfectly even scores better than averaging out correct while lurching between fast and slow gaps.

Daily total

Your five rounds add up to a score out of 500. That total is what you share, and what keeps your streak alive when you play each day.

Practice bests

Outside the daily, each mode tracks your best run average, so you can chase your own record without spending your one daily shot. Practice bests and daily results are stored separately, and neither is sent anywhere; they live in your browser.

What to aim for

For most people a first run lands somewhere in the 70s and climbs into the 80s within a few sessions, largely by removing a systematic bias rather than by getting mysteriously sharper. Averaging above 90 across five rounds means you are consistently inside 10 per cent on every discipline, which is a genuinely good result.

If you want to move the number rather than admire it, how to improve your sense of time is the practical guide. The fastest gain available to almost everyone is correcting a bias they didn't know they had.
