The condensation is kind of a head scratcher all right!
I don't have an HG and folks that do will have to give you specific advice re: suspension tightness. With my full length JRB MW, I have just adjusted it so it felt snug against my back on either a WBBB or a JRB bridge hammock, and have been plenty warm as low as 10F. It has a suspension that simply attaches from the ends to the hammock. I did have to fiddle quite a bit to get the fit correct on the foot end with the WBBB, but once I got it all was fine.
But on my torso length WB Yeti, which has an encircling or perimeter suspension ( don't know if that is related ), I have to make sure that it lifts my empty hammock in the middle 2 or 3 feet to get full performance out of it. And I have to make sure the head end edge of
the quilt is right about my neck line. I can get away with a bit lower, but even an inch or two higher and it starts venting, allowing cold air to flow right down the middle. But I don't know how things work with an incubator. I'd say at the very least, make sure it is not too loose, that it is at least nice and snug against your back and butt. It sounds like you also need to work on the leg end adjustment, but I'm not sure how to do that with your full length UQ.
Did you notice any difference in top warmth vs bottom warmth?
I think the condensation was a main player in your weak results. The question is: why so much condensation?
1st, did you have a tarp and was it covered inside in condensation?
Were you in your back yard
, over grass in a more or less wide open, unsheltered area, under clear skies? Under conditions like that, I often get tons of condensation, even if I am not in the hammock. I have come out to cold weather test to find my MW4 covered in a thick layer of frost, as well as any uncovered hammock and the inside of my tarp. It appears that ground moisture rises up and condenses, but I really don't know. I have never had this issue out in the woods, on an actual backpack trip. Only in my backyard.
However, I guess the good news is that this condensation seems to be pretty much outside on the shell. The other kind comes from your warm body moisture condensing not only on the shell, but in the outer layers of the insulation, even with a breathable shell. Heck, it can condense on your mossie net, which is pretty darn breathable. I know that is a problem when it is very cold, but I'm not so sure about at 39F. Anyone care to opine about that?
Then again, the one time I had bad condensation in my HH Super Shelter, it was only in the high 40s, so maybe it can be a bad problem. But that was different. It was not a matter of it condensing in my bag or quilt or the breathable shell, but of condensing on the inside of my cold outer layer water proof sil-nylon shell ( the under cover ). So, kind of different.
