In principle, yes. And involving buoyancy, definitely. Mask, regulator or airsharing drills, perhaps not so much. And inflating buddy's BCD and dropping weights on the surface is usually best done... on the surfacejust a lowly freshly minted OW stroke here... but am the only one who this raises a big red flag with?
in OW, we were taught to do any drills involving buoyancy at the start of the dive, when tissue gas loading is at its lowest.
When or if you're riding the NDL? Everybody isn't riding the NDL at the end of every dive, you know. Just for the record, we (deliberately) had a very good margin. From eyeballing my multilevel profile, I'd guesstimate that I was in the O to R pressure group myself.the risk factors involved are lower when you're only working with a few minutes worth of shallow ongassing, rather than when you're riding the NDL at the end.
