Definitely not. It's a great base to start from, then you can improve upon it with more slider + penalty values, which is what I focused on.
You will still see small instances of warping, but not as consistently. It really is quite amazing from an animation perspective, when there seems to be much less magnetic interactions. I'd rather try to eliminate any chance of warping, poor collisions, suction blocking, from happening than to allow it. Threshold isn't the only tool for this - but it's a primary base for me this year.
