I have the admit as an active nitrox instructor for ssi, I don’t really know the answer to the op’s question.
It has always been my habit to issue the 40% cert. there is indeed 4 sections to the book and online manuals. I have always taught all of it as I believe it is all relevant to anyone diving nitrox. The instructor manual does not make mention of nitrox 32 vs nitrox 40 that I can see. But there is the option in ordering the cert card for either one. It’s a question I will bring and will post when and if I can get an official answer.
