I suspect wort density also plays a role, if only because when I was carbing "thick" stouts pre-beergas days they took a lot longer to reach ~ 2 volumes than a pale or even IPA.
iirc, Chris White's Yeast benchmark O2 metric was 2 minutes at 1 lpm. When I picked up an O2 tank and medical flow meter rig I went with .5 lpm for 4 minutes stirred in with a Williams .5 micron wand. And while I don't adjust for OG it still seems to work well enough...
Cheers!
