Good point. You don't turn on every punch, but you do throw every punch with proper technique. I remember watching Julio Cesar Borboa ko Gilberto Roman's little brother- moved in and out, punching crisp and hard, but never once 'setting down' on a punch. He won in 4. Orlando Canizales was good at this as well, moving and hitting hard (because his balance was spot on and his technique just right) then turning on a punch when he had it set up. Arguello, too.
