now let's compare this with other typical bindings that use a disc cover that screws on
4 mounting screws + 1 screw
yep, clearly 9 or 7
I think what he's saying is he's canting the footbeds so much that he has to mess with the four cant adjustment screws just to pull the footbed off. Four cant screws + one footbed screw + four baseplate screws = nine screws. If you're canting the footbeds enough to make it hard to pull off, that's waaaaaay too much canting IMO.
