Hi Branden, no problem I'm glad that looks like it should work for you.

It's probably not going to always be a better success rate, but if I remember right what happens is if the object started out as a solid and after the fillet it isn't a solid anymore, it tries to do it again with a tightened up tolerance in the hope that will help getting pieces to align with each other better. But in this particular case here it ends up being worse when that happens.

No, it's not doing any special work to guarantee that it's tangent but with all the edges being tangent it's going to be extremely close.
