The point that Butch is making is that a very smooth surface (think a polyurethane finish on a basketball court ripping your skin off)

Unprotected riders will leave more skin and flesh behind on a rough road surface than a basketballer will leave imbedded
in a polyurethane coated basketball court. To say those two surfaces are accomplishing the same thing/ result is nonsense...

Maybe You or Butch can explain how smooth glass or a smooth polyurethane finish creates/contributes to more fouling...???

AGAIN, , better to show the science-physics that supports the claimed theory that smoother surfaces create more fouling,
..but nobody seems able to provide such.


Coefficient of friction. Two smooth surfaces have much more bearing surface causing friction. It's the same thing that allows a boat to travel much fast on slightly choppy water. When we are talking about a "rough" bore here, we aren't taking about rough in the sense of sandpaper stripping the copper jacket from the bullet. Only "rough" enough to reduce the friction.....
