But sir, if I change one component of my car that influences all the components that I have previously had certed and were working in harmony why does this one component's relationship with all these other components need to be checked?
I built this table with four legs the same length and I've had those legs certified, but now I've put a new top on the table that I've attached to said legs with bubble gum and two of the legs don't touch the ground anymore, but why should the certifier check the legs again??
