What I mean to say is to still apply just one dose of O2 but to do it fairly soon after pitching rather than to oxygenate, lose some O2, and then pitch.
For instance, if I brew a lager, I like to chill and rack off the break material before pitching the next morning. So if I oxygenated the night before pitching, I'd lose much of my O2 by the time I did pitch. If I wait until after I pitch, the yeast take it up immediately. No waste. Right?
