You think less than a point difference in buoyancy really makes a difference? For a close to properly weighted student (key words "close to properly weighted") .77 lbs isn't noticeable.
When I weight my students, I do it in 2 lb increments, as I don't have half pound weights. Maybe I should cut a couple 1 lb.'ers in half then? As theoretically, a student could be 1.5 lbs overweighted as taking off two pounds could make them 0.5 positive with a nearly empty cylinder. Of course this could be compensated by breathing, but that's not the idea in proper weighting.
The issue here is that the deceased was so extremely overweighted, weight wasn't ditchable, didn't have the dry suit hose that might have helped (I say might the deceased was likely so extremely foot heavy that if she did have the inflator hose, her neck seal would likely burp allowing water in and not provide much positive buoyancy), didn't have a pool session with the dry suit, etc., etcl.
If we shaved off 0.77 lb from the weight she had, she'd still have died.
I don't think the elevation argument is valid period. When I hear that argument being placed, I interpret that the person either isn't a diver or doesn't understand physics and the potential buoyancy swing from lungs.
