How Perceptle scores work
Each test earns 0–100 points from the size of its error. This edition uses a smooth, gradually decreasing curve, so small misses retain high scores and larger misses lose points progressively. The full-round total is the rounded average of the five test scores.
Use the correct error unit
Count divides the numerical miss by the true quantity. Track measures a horizontal miss in logical board pixels. Angle measures degrees, using the shorter circular gap in normal mode and accumulated turns on Friday.
Split divides the placement miss by line length. Tempo separates a steady interval difference, irregular jitter and entry phase, then scales its tolerance with the target period. A low rhythm score is not a ten-point scale.
A curve with understandable steps
The score is rounded from 100 ÷ [1 + (error ÷ (1.5 × tolerance))²]. At half, one and one-and-a-half tolerance units, that gives approximately 90, 69 and 50 points.
Normal tolerance is 20% for Count, 60 logical pixels for Track, 8° for Angle and 5 percentage points for Split. Tempo’s normal tolerance is 10% of the beat interval; its combined error also includes jitter and half the entry-phase error.
Grades and comparisons
Grades are S at 95 or above, A at 85, B at 70, C at 55 and D at 40; lower totals receive F. The same boundaries apply to an individual test and the rounded full-round average.
Use the calculator to explore one controlled error at a time. An actual Tempo attempt can include several timing errors together. Previously saved records retain the score calculated when they were played.
| Test | 90 / 100 | 69 / 100 | 50 / 100 |
|---|---|---|---|
| Count | 10% | 20% | 30% |
| Track | 30 px | 60 px | 90 px |
| Angle | 4° | 8° | 12° |
| Tempo | 30 ms | 60 ms | 90 ms |
| Split | 2.5% | 5% | 7.5% |

Questions and answers
Are five scores added to make 500?
The result shown here is their rounded average out of 100. For example, five scores of 90 produce a total of 90.
Does a small error immediately make the score zero?
No. The curve decays continuously before rounding. For example, normal angle errors of 4°, 8° and 12° give about 90, 69 and 50.
