🖱️ 回報率（Polling Rate）是什麼？怎麼看結果？
🖱️ What is Polling Rate and how to read the results?
回報率代表滑鼠每秒向電腦回報位置的次數。數值越高，滑鼠移動的傳遞越即時。
Polling rate represents how many times per second the mouse reports its position to the PC. A higher value means more instantaneous tracking.
- 125 Hz：間隔 8 ms，入門有線滑鼠預設值8 ms interval, default for budget wired mice.
- 500 Hz：間隔 2 ms，一般電競入門2 ms interval, entry-level gaming.
- 1000 Hz：間隔 1 ms，主流電競標準1 ms interval, mainstream gaming standard.
- 4000 / 8000 Hz：間隔 0.25 / 0.125 ms，高階電競滑鼠0.25 / 0.125 ms interval, high-end esports mice.
測試時請持續大幅度移動滑鼠至少 3 秒。若 Avg Hz 明顯低於標稱規格，請檢查滑鼠驅動程式設定。
Move your mouse continuously in wide circles for at least 3 seconds. If the Avg Hz is lower than advertised, check your mouse software settings.
穩定度（Stability）怎麼解讀？
How to interpret Stability?
穩定度反映回報間隔的一致性。95% 以上為優秀；80–95% 為正常；80% 以下可能代表 USB 頻寬不足或無線訊號干擾。
Stability reflects the consistency of the polling intervals. 95%+ is excellent; 80–95% is normal; below 80% may indicate USB bandwidth limits or wireless interference.
點擊反應時間代表什麼？
What does Click Response Time mean?
量測「按下滑鼠鍵」到「瀏覽器繪製下一幀」的時間差，是輸入管線延遲的瀏覽器層級估算。數值與螢幕刷新率相關（60Hz 約 8–12ms、144Hz 約 3–7ms）。若數值明顯偏高或跳動劇烈，可能是背景程式佔用 CPU 或 USB 頻寬不足。
Measures the time from mouse button press to the browser's next rendered frame — a browser-level estimate of input pipeline latency. It scales with refresh rate (~8–12 ms at 60Hz, ~3–7 ms at 144Hz). Consistently high or spiky values suggest CPU contention or USB bandwidth limits.
⌨️ Input-to-Frame Latency 是什麼？
⌨️ What is Input-to-Frame Latency?
這是從「按鍵訊號送達系統」到「瀏覽器準備好繪製下一幀」之間的時間差，反映輸入在軟體管線中的傳遞延遲。此數值與螢幕刷新率密切相關：
This is the time difference between the keystroke reaching the system and the browser rendering the next frame. It is heavily tied to your monitor's refresh rate:
- 60Hz 螢幕60Hz Monitor：平均約 8–12 ms（按鍵平均等待半幀）Avg ~8–12 ms (keystroke waits half a frame on avg).
- 144Hz 螢幕144Hz Monitor：平均約 3–5 msAvg ~3–5 ms.
- 240Hz 螢幕240Hz Monitor：平均約 2–3 msAvg ~2–3 ms.
為什麼數值會跳動？
Why do the numbers fluctuate?
螢幕刷新與鍵盤輸入是非同步的。按鍵若剛好在幀刷新前 1ms 觸發，延遲就很低；若是刷新後觸發，就需等待下一幀。這是物理上的必然，重要的是觀察「平均值」是否符合您的刷新率。
Screen refresh and keyboard inputs run on asynchronous clocks. If you press a key 1ms before a frame refreshes, latency is tiny. If after, it must wait for the next frame. What matters is the "Average" aligning with your refresh rate.
什麼是 NKRO？我的鍵盤支援嗎？
What is NKRO? Does my keyboard support it?
NKRO（N-Key Rollover）代表同時按下任意多鍵都能正確識別，不發生衝突。測試方法：同時按住 5 顆以上按鍵，若全部出現在畫面上即代表支援。
NKRO (N-Key Rollover) means pressing any number of keys simultaneously will be correctly registered. To test: press 5+ keys at once. If they all appear on the screen, you have it.
按鍵重複延遲 / 速率怎麼看？
How to read Key Repeat Delay / Rate?
長按一個鍵，系統會先等待「首次延遲」再開始自動重複。Windows 預設約為 500ms 延遲、每秒 30 次（間隔 ~33ms）。此處量測的是您「目前作業系統的設定值」，可在系統設定 → 鍵盤中調整；若數值與預期不符，可能是驅動程式覆蓋了系統設定。
Hold a key: the OS waits an initial delay before auto-repeating. Windows defaults are ~500 ms delay and 30 repeats/sec (~33 ms interval). This measures your current OS setting (adjustable in Settings → Keyboard); unexpected values may mean a driver is overriding them.
🎮 死區（Deadzone）是什麼？如何測試？
🎮 What is Deadzone and how to test it?
死區是搖桿中心周圍「不產生訊號」的範圍，用來過濾靜置時的微小漂移。將搖桿緩慢繞圈，觀察左側死區圓形圖的軌跡：軌跡應呈現均勻的正圓形，且中心有清晰的空白區域。
The deadzone is the area around the stick's center that ignores input, designed to filter out micro-drift. Move the stick slowly in a circle and watch the left graph: the trail should form a smooth circle with a clear blank spot in the center.
什麼是圓形度誤差（Circularity Error）？
What is Circularity Error?
圓形度誤差反映搖桿回報的精準度。用力推到底繞一圈，10% 以內誤差屬可接受範圍；超過 15% 可能影響賽車或射擊遊戲的表現，可考慮在遊戲設定中調整死區補償。
It reflects the stick's reporting accuracy. Pushing it to the edge and doing a full rotation should yield <10% error. If it exceeds 15%, it might affect games requiring precise inputs. You can compensate in-game.
搖桿飄移（Drift）怎麼判斷？
How to check for Stick Drift?
雙手離開手把，觀察畫面上搖桿中心點是否持續偏離圓心。若有固定方向的偏移，代表搖桿電位器已磨損，需清潔接點或更換搖桿模組。
Take your hands off the controller and observe if the on-screen stick dot drifts away from the absolute center. A persistent offset indicates worn potentiometers.
