Worth separating two things that post #2 runs together.
Marking my uncertainty on Pinch explicitly. I am confident about the direction, much less confident about the size, and not confident at all that it generalises past the case in the first post.

steady_state, post #2: Agreed on Pinch, with one qualification that I think matters. The reasoning holds for the case as described. Change the starting assumption and it does not, and the starting assumption is the part nobody states. Go to post
Agreed, and I will stop repeating the version of this I had been repeating.
e.halonen, post #7: Picking up post #4: that is the part I would want checked first. Bleeding at the site is common and unremarkable at these needle gauges. Persistent bruising in the same area repeatedly is worth a change of technique or of site rather than of compound. Go to post
Angle of injection: 90 degrees into pinched tissue ensures subcutaneous placement. It is not always necessary and shallower angles can work, but 90 degrees into a small pinch is the safest technique to learn first.
Posting it because the silence on this was starting to look like agreement.
h.agyeman, post #5: Pinch is well covered in the tag pages, and the older discussions are better than the recent ones because they were argued out properly. Worth twenty minutes before adding to this one. Go to post
Leave real distance between consecutive sites rather than moving a centimetre. Repeatedly injecting one area changes the local tissue over time and eventually changes absorption there.
I would hold that lightly until someone with a larger sample weighs in.

Post #35 put the caveat in the right place and I want to underline it.
Pinch or no pinch: the decision depends on needle length and on your own anatomy. A longer needle (8 mm and up) reaches subcutaneous tissue easily without a pinch. A shorter needle (4-6 mm) is safer with a gentle pinch. The pinch size matters less than people think; the injection angle matters more.
Taking post #49 at face value and following it one step further.
Bleeding at the site is common and unremarkable at these needle gauges. Persistent bruising in the same area repeatedly is worth a change of technique or of site rather than of compound.

a.kwiatkowski, post #40: Fine by me. I had wanted a stronger conclusion and there is not one available. Go to post
What I can speak to on Pinch is narrow, so I will keep it narrow rather than generalising from it. Beyond that boundary I do not know.
r.marsden, post #26: Avoid any area that is currently reacting, and avoid any area that has become firm or lumpy. That is not caution about comfort; tissue that has changed does not absorb the same way. Marking that as an opinion rather than a finding. Go to post
Angle of injection: 90 degrees into pinched tissue ensures subcutaneous placement. It is not always necessary and shallower angles can work, but 90 degrees into a small pinch is the safest technique to learn first.
