Most people seem to have already guessed it. My point is that because Groves is impossible to track down, there is no accounting for his work. We only have Aulis' statement that he actually is qualified to do what was claimed, that he actually did what was claimed, and that the results they present us are what were actually obtained. Without Groves standing up and being counted and having his work examined, he is an anonymous authority, i.e. worthless.
The fact that a number of people, including those predominate in the Hoax debunking community, have tried to track him down and keep running into dead ends and ghosts doesn't mean he doesn't exist, but it certainly means he's not publicly accountable for his supposed claims. Since he apparently isn't willing to stand by his work, show that he was indeed qualified to make the assessments he had and support his conclusions, why should he be accepted as an authority? He shouldn't.
As I wrote earlier:
... the credibility and validity of Groves' analysis is not, I don't believe, at all dependent on his qualifications or expertise, with very limited exception. It's essentially a mathematical analysis, so should stand or fall on its merits.
You can, therefore, call off the dogs, and put aside whatever the logical fallacy of the converse of 'appeal to authority' is (appeal to unauthority?!).
As to the image, not being sure which it was comes from not wanting to reading form a dozen rambling posts.
Oh no, no point wasting time checking out what the debate's about before wading in with consequential erroneous views, is there!

That a boy!
I make the mistake of assuming it was Groves "hotspot on the boot" claims with the Aldrin egress image that were in discussion.
Yes, making wild assumptions can have a tendency to cause problems!
Since it seems it's the "Man on the Moon" image ...
'Seems'? Oh no, it actually
is the 'Man on the Moon' image we're talking about, believe me, it's reality! (Jeez, who's the skeptic here?!)
... then all I can say ...
Yes, I didn't expect it to extend to more than a few words, but let's see:
... is Aulis' work on this is even worse. They use a poor publicity image rather than getting an original scan and things get worse from there.
'Get worse from there'? What do you mean? Let's see:
The reason that Armstrong is "above" Aldrin is two fold. Aldirn is standing in a depression (you can see it in the photograph) ...
I commented on this earlier. He's hardly 'in a depression' - towards the lip of of it, if you ask me. But it doesn't matter, Groves takes account of the surface height difference.
... while the ground Armstrong is on is higher ...
Er, yes, that would be a logical conclusion to draw - Aldrin's lower, so Armstrong must be higher. 10/10 on that part!
... and second, Aldrin is leaning towards the camera. The centre of mass of the suits caused the Astronauts to lean forwards. Good shots of this are the "Aldrin Flag Salute" images were the lean forwards is showed very clearly.
How does that put Armstrong 'above' Aldrin? Did Armstrong have a unique spacesuit that prevented the same thing happening to him?! In fact, the photographer is also leaning forward (or looking down), hence the position of the centre cross-hair over Aldrin's right ankle.
As to my assessment of the book "Dark Moon", I stand by it, it is a muddled, incoherent, poorly thought out, self debunking, load of trash that isn't worth being used as toilet paper.
And this coming from somebody predisposed to writing what we read above!
