Controller Reliability Dashboard
142,850 documented test results across 5 tracked controller models (snapshot 2026-08-02). Every bar on this page is rendered directly from the baseline dataset — no derived figures.
Avg 12-Month Stick Drift
Static offset at rest after 12 months, by model baseline. Lower is better.
Avg Circularity Error
Deviation from a perfect outer circle at full deflection. Lower is better.
Avg Drift-Free Lifespan
Months before drift crosses the >2.5% deadzone-tuning threshold. Higher is better.
Dataset Composition
Share of documented results per model. More samples = sharper baseline.
Drift Magnitude Percentile Thresholds by Model
The tier cutoffs used by the Health Score and drift percentile math. Thresholds are drift % at rest.
| Model | Excellent | Good | Average | Poor |
|---|---|---|---|---|
| PlayStation 5 DualSense | 1.5% | 3.2% | 5.8% | > 5.8% |
| Xbox Wireless Controller (Series X/S) | 1.8% | 3.5% | 6.2% | > 6.2% |
| Nintendo Switch Pro Controller | 1.2% | 2.8% | 4.5% | > 4.5% |
| PlayStation DualSense Edge | 1.4% | 3% | 5.5% | > 5.5% |
| Hall Effect Controllers (8BitDo / Gamesir / Flydigi) | 0.05% | 0.2% | 0.8% | > 0.8% |
Where this data comes from — and its limits
This is a static baseline snapshot, not live telemetry. The dataset is aggregated from 142,850 documented test results (snapshot 2026-08-02).
Your own telemetry stays in your browser: when you opt in to the consent prompt on a diagnostic tool, your measurements are logged locally (ct_telemetry_log) so you can track your own controller over time — nothing is uploaded. The live, first-party dataset grows as we are able to publish new snapshots, and every snapshot is dated so the numbers can be checked.
