Perceptle tips: improve the judgment behind each score

Try seeing groups of five or ten rather than recounting the whole field. An uneven field needs uneven quarter estimates. If actual counts of 55, 70 and 60 become guesses of 50, 64 and 54, you have repeated underestimation to investigate; one miss alone would be less useful.

In Friday, make a population estimate rather than adding snapshots of moving dots. Read the Count method and scoring example.

Before tapping, name the stage of the visible arc. If the ball is rising, allow the remaining climb as well as the fall. If it is falling close to the ground, do not extend its horizontal travel for a whole extra arc.

On Friday, trace the wall reflections. A landing expected beyond the right wall may reflect back into the middle. Compare your chosen and actual positions on the same internal field, not raw screen pixels. Use the Track examples.

For 110°, place a quarter turn and add about 20°. For 579° Friday, count one full turn and then 219°. Say both components before moving.

Use the dashed starting ray. In Normal, a 358° direction and 2° direction are only 4° apart. In Friday, 90° and 450° remain a full turn apart. Change complete turns in the angle tool.

At 100 BPM, aim for intervals near 600 ms. Eight taps all 100 ms late can still have steady intervals; growing lateness suggests a slower continuation. Alternating early and late suggests jitter.

Keep the same speaker/headphones and input method when comparing. On Friday, shift into the half-beat gaps without doubling the rate. The original warm-up calibration differs from fixed-reference practice. Inspect separate timing measurements.

For 3/8 from the right, the left-based position is 5/8, or 62.5%. A mark at 37.5% is mirrored; 57.5% is on the correct side but five percentage points short. Fix the first by reading the endpoint; fix the second by improving equal subdivisions.

For Friday 3/2, first go one whole line then another half beyond the correct end. Try a right-end extended target.

1. Choose one skill and one change.
2. Record five new targets, answers and directional errors.
3. Compare the middle absolute error, not just the best score.
4. Keep the mode, difficulty, device and input method comparable.
5. Return to the original daily or a dated Archive set to apply the judgment.

This is a practical self-check, not a promised improvement rate. Original Keep playing supplies fresh complete sets; companion exercises isolate Normal skills. A target-grade plan shows a mathematical route to A or S, not which skill you will improve fastest.
