He didn't say regular dust, he said "wear dust" from the cam sensor. That's pure speculation to assume there would be any "wear dust" at all let alone if that it would actually be be signifigant relative to the current normal dust problem and to proclaim green button as "optimum" for K/M for that reason. He doesn't have any reasonable basis to make that kind of conclusion. jco
