This reminds me of a buddy of mine who was one of the Campagnolo tech support people for the bike events at the 1984 Los Angeles Olympics.
He would take a Campagnolo chainring and put these really nasty scratches in a Shimano DuraAce chainring and then take the DuraAce and try to do the same to the Campy chainring and nothing would happen. When I say "a Campagnolo chainring" I mean any Campy chainring from the cheapest group to the most expensive; no difference. Even the cheap Campy rings were made of the same stuff as the Super Record/ C-Record rings.
As they say... "First hand experience!"
