Stick Motion Resolution Analysis

This test evaluates the analog stick's ability to register unique positions during a controlled, linear motion from the center to the edge of its range. The analysis was conducted using the Line program, ensuring precise measurement of the stick's resolution, linearity, and response characteristics.

Data Points

Data Points represents the total number of unique positions registered during the smooth movement of the stick from center to edge. This includes both the stable analog values and positions affected by signal processing or jitter. In this test, we recorded 161 data points, which is an excellent result that indicates very precise stick movement registration. For a more accurate assessment of stick precision, it's important to also consider the Straight Points metric, which filters out noise and signal processing artifacts.

Straight Points

Straight Points represent the number of unique positions detected after filtering out tremor and signal processing artifacts during stick movement. This filtering process identifies points that follow a consistently increasing trajectory, showing the true analog values without noise. The test registered 121 straight points. This is an excellent result, indicating very smooth and precise stick movement. This value highlights the stick's ability to provide stable and reliable position data during smooth motion.

Resolution

Resolution in this test refers to two complementary measurements:

Total Resolution: 127 positions across the entire stick range. This number represents how many distinct positions the analog stick can detect from center to edge. This might result in somewhat stepped or less smooth movement

Step Resolution: 0.00784 per increment. This value represents the average size of each step between detected positions (smaller values indicate higher precision). It determines how smoothly the stick can transition between positions, which directly impacts precise aiming and subtle movements in games.

A high total resolution combined with a low step resolution provides the optimal experience for precise control in games requiring fine adjustments.

Tremor

Tremor percentage represents the amount of signal processing that occurs between raw stick movement and the final output. It is calculated as the percentage of data points that don't follow a consistently increasing trajectory. The test measured 24.8% tremor. This represents typical noise levels in stick signal processing. Different controllers have different signal processing characteristics, and lower tremor values typically indicate more direct translation of physical movement.

Linearity

Linearity represents how closely the stick movement follows an ideal linear path. It's calculated as 100% minus the nonlinearity percentage, where nonlinearity measures deviations from a perfectly straight line. The test measured 94.5% linearity. This indicates excellent stick linearity, providing consistent and predictable movement.

At the same time, a gamepad stick is not a perfectly linear mechanical system. The stick rotates around a pivot, the cap travels along an arc, and the sensor reads that rotational movement rather than a truly straight physical path. Because of this, a graph that bends slightly below the ideal straight line is often normal. In many cases, that lower arc-like bow reflects the real mechanics of the stick more faithfully than a response that was tuned mainly to look perfectly straight in this specific test.

What matters most is that the movement remains smooth, progressive, and predictable. A mild, even downward curve can be acceptable or even technically more natural, while sharp dips, waviness, uneven acceleration, or asymmetry still indicate worse response quality. For easier interpretation, the chart includes a soft highlighted reference zone under the ideal line. It marks a typical range where a small arc-related deviation is considered normal and serves as an informational guide rather than a strict pass/fail boundary.

Test Duration

The time taken to complete the test was 9.59 seconds. This is an optimal test duration, providing reliable results. For the most accurate results, the stick movement should be smooth and controlled, typically taking between 5 and 8 seconds.
