Not sure of how much it's a bug or not

Summary

I wasn’t sure if this would be considered a bug, or just limitations of the Autosolve, however, I put several characters through a quick test. Obviously, some have a bit TOO much of things, like Big Hair, etc.
However, one was a simple, bald female character, and granted her palms were facing outward, but the first round they went fine, but the feet never stretched to meet the existing targeted mesh. So, I reran the autosolve, and bam, the feet nailed it, BUT the hand all of sudden exploded inwards, etc.
Some of the other meshes are let’s say, uber skinny, and the face wouldn’t track, so, a mess there.
Anywhoo, just wondering how far this can be pushed, and what are the parameters we should be realistically be hitting, e.g. palms inward, A pose, no clothes or pretty scantily dressed, no hair?
Can the toons be humanoid, bipedal, but nothing crazy, like a crystal beast(i’ve yet to try this one).
Just wondering for character development as I’m sure many are as well.

Steps to Reproduce

I reran, autosolve, tried different versions of the same model.

Expected Result

After running the autosolve several times, the final mesh was very messy, not at all what I’d expected.

Observed Result

The feet wouldn’t meet the targeted source mesh, but the hands would fit perfectly. If I re ran it, the feet would hit, but then the hands would go haywire.

Additional Notes

For the green, Zombie like character, it immediately failed the facial tracking.
