OK, I'll rephrase the question, if they want to be defensive about answering a plainly-worded question:
Given that the same brand name is found on two wildly different formulations, indistinguishable except in the fine print on the label, who's killing more varroa, with less collateral damage? The guys with "double the dose", or "half the dose"?
Is it:
1) "based on our experience, on the experience of Italian beekeepers" in the EU at a 0.0434 g/ml dribble dose? (per my prior post)
2) "the USDA" in the USA, at a 0.024 g/ml dribble dose (per prior post)
3) The guys who use roughly 100% Oxalic from the hardware store, follows the Marion Ellis protocol, which was based on pure Oxalic, and ends up with a 0.025 g/ml dose? (see below on this one)
And does any of this matter to the Oxalic vaporizing crowd? I think the lack of complaints other than mine points to a wild variation in temperatures from the various vaporizers. The residue I was seeing in my little vaporizer was clearly due to the specific impurities in the "approved" 97% product, not found in the generic ("pure") chemical, but I guess no one else noticed... what does that say about their temperature control? If they are burning off the sugar to the point that the residue disappears from the heated metal, what's THAT temperature? I'll guess that the 86% stuff is going to leave more residue than the 97% stuff, so the Europeans should have raised a flag on this before now.
...And why do I have to be the one to wander by and stumble over multiple basic, significant, and silent disconnects over what is presented as a single bee veterinary product? I'm happy to listen to those who did not sleep through most of biochem like I did, but somebody please tell me - What's The Freakin' DOSE Here? Or does "the dose" simply not matter that much, despite the warnings of the need to worry about precise measurement "to the gram", even at the "1 Liter" batch level.
And puhleeeze - don't presume to lecture me any further about "the label is the law", unless the labels are accurate about "what's in the box" and a little more consistent about "dose" than one dose being DOUBLE the other for the same pest on the same bees!

"informed discussion" means you show your data and/or math
So, for (3) above, using "pure" uncut Oxalic, we still have to "dehydrate the dihydrate":
water 18.01 g/mol
sugar 342
C2H2O4.2H2O 126.07
C2H2O4 90.3
600 grams each of water and sugar yields 1002 ml of solution
All 35 grams are pure Oxalic dihydrate, so no de-rating required.
35g * 126.07 / 90.3 = 25.06
25.06 / 1002 = 0.025 g/ml dose
As one would expect, 100% is not much different from the 97%, but if this is true, why all the mumbo-jumbo over the critical nature of precise measurement? Beekeepers have been told to use scales considered "drug paraphernalia" in most jurisdictions, and they measure out a "white crystalline substance" with them into (ooops!) small plastic bags. ("Gosh officer, I'm just a beekeeper, and these drugs are medicine for my bees! Where are my beehives? Up on that roof... no you can't see them from here...")
