Astonishing as it seems, some of us don't rely on belief. It's a matter 
of doing the math on the bearing load and friction differences between 
a 1° or less downbearing on the bridge top and the two 10° or so bearing 
and friction loads at the bridge pins. Making an attempt to actually 
quantify these forces indicates to me that bridge cap friction is 
comparatively inconsequential. The visual aspect is certainly real for 
notching, but it needn't be a lubricant.
