Did you go through the attachment he provided? It provides the basis for how someone (who may choose to use a thick wetsuit) might arrive at the optimal amount of ditchable lead.No, my earlier comment was completely accurate. That's not a good reason to carry extra ditchable weight (although I'm aware that some divers do it). As I already pointed out in an earlier comment, if your wetsuit is thick enough to cause a problem getting up with a failed wing then the correct solution is to use a proper shell drysuit rather than carrying extra ditchable weight. This is part of having a balanced rig.
I don't think anyone has advocated for carrying more lead than necessary - just so it can be ditched. The question is rather, what portion of the diver's ballast ( primarily lead) can/should be ditchable and this obviously pertains primarily to recreational - no deco profiles.
