Those number for side clearance are in mm and not inches, so for example .002" = .051mm is within range. |

One would hope that NASA had a Quality Assurance program that would be able to tell that the 'course corrections' they were making were just making the situation worse ...

It seems like things are in spec and check out (It's super weird that everything checks out, yet the fluid leaked so much)...
You should do a hone job on that cylinder before putting it back together if you can to give those rings a fresh surface to seat to, the cylinder wall is looking shiny, maybe it wasn't honed properly by whoever was in there last and it didn't "seat" well?
Watch Uncle Tony here, he's got some good info in his videos... Here's some about honing and inspecting the cylinders...

Thanks for posting. I'll try that ring position test with the flashlight pointing up from the bottom to show out-of-round areas! I don't think I'm up to honing with gasoline ... WD-40 perhaps. Uncle Tony has a lot of good tips there.

Update: I looked for out-of-roundness with the top ring, using the piston to move the ring down about one inch at a time (per Uncle Tony), with a light at the bottom right beneath the crank. I ran the test twice: once with the ring gap clocked at Noon and once at 3PM. Both showed no light leaks around the ring edges. I can definitely see that the area swept by the bottom-most "point" of the piston is highly polished, with no remains of the cross hatch pattern (i.e. corresponds to region between the Red Arrows). This is about the only feature of the Bore that seems suspect to me.
