Using the constrained stiffness solver is a good idea, because it "decouples" the stiffness from the time and solver steps. "Better" at rougher settings, "worse" at finer ones, but in this case "worse" is good, as it means more stretch.
Let me preface the following by saying that tyFlow is an incredible piece of software and Tyson should get some kind of lifetime achievement award for improving 3ds max so much. I'm also far from an expert in tyFlow and not a technical artist to begin with. TyFlow also offers a lot of other tools to fix things.
However, I do think cloth (being only a small part of tyFlow, which is not a dedicated cloth solution) has quite a few issues. Free flowing or single trick motion design things work fine, but for things with several constraints, e.g. actual clothing beyond skirts etc., it's a struggle and very glitchy. Better tutorials can help to a degree, but that can't solve some of the basic problems.
I understand cloth is hard to do in general and have a rough idea of why e.g. stiffer cloth is prone to twitching (even more so than normal settings), but for example in this case, yes, it's overstretched, but what happens in the collision area simply shouldn't. It should "fail" more gracefully.
