Yeah, it seems that edges that meet at 90 degrees or higher are handled fine, it's the ones sharper than that from triangular holes that are not handled properly.

Let me know if you would like me to cook up a version with the .25 value, using that alternate method Offset + Loft method. I can complete that partially finished version that I posted earlier if you want.
