只能說大大真勇者辛苦了
-----------以下都廢話,懶得看可跳最後-------------------
記得當初開始集資時~~有朋友在問我都勸不要下手先觀望
最主要是用去氣嘴蓋測功率跟轉速原理講得不清不楚
最一開始還講出是利用"皮托管原理"加上獨家的計算
(我是搞不懂,測氣体的流动速度,跟功率有什麼關係 )
不過現在好像都沒再提到了
但現在他們的網站很巧妙地寫
是靠簡單的氣壓測量與G力感應器
加上CPU的計算能力與細心調校的預測模型
老實說我懷疑 這只是靠G力感應器加上輪徑測量出速度
剩下的數據只是靠速度估算出來的
這也可以解釋為什麼平路誤差大
平路: 不可測的影響因素多,光順風逆風就差很多
爬坡: 影響因素少,主要就體重跟坡度,用專用車錶有坡度數據,改善幅度大是可期的
下坡: 就真的沒得計算了
-------------------------------- 以上都廢話 --------------------------
結論是...我認為這東西只能測量速度
其他的數據,是根據速度計算出來的
(而且官網的描述,有巧妙的暗示,懷疑是準備事後規避責任)
另外要感謝 ecszero 身先士卒跳坑為大家測試 XD
