If your thinking is to get it aligned properly no matter what it takes, then you are thinking correctly. Never heard of someone describing a fit with percentage. The is no quantitative spatial value for those trying to visualize and help.
You are good to go with 3/16 bracket at bottom. It does all the mechanical holding and alignment. The long bar is just for tension adjustment but you can see it tell tales the misalignment.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
