And why did you explain me how does CoC work , if I explained it in another comment ? Look , I never said that CwC with respect that way , all the paragraph has an IF at the beginning , it ' s conditional . By the way , your example of CwC is wrong , the first spell is fired at 0 . 5 s , check the last lioneye talk with Rory . <| sep |> You mean like prayer ? <| sep |> Actually , this asset is closer to what you ' re talking about than chronos . <| sep |> All that effort and the mission fails because a redundant sensor breaks and throws and invalid value ? How do you not account for hardware failure , jesus christ I expect the sensors on my DIY drone to fail every once in a while , and I compensate for that in the combined estimation . Holy shit the ESA is a fucking disappointment
