The fabricator will know the bend allowance ( or deduction) that works for them The fabricators I use will give me a bend allowance (deduction) for a given material / thickness - i.e. No bend allowance for Stainless Steel & 0.6mm for a 90 deg bend in 2.0mm Mild Steel. I set the Radius to be equal to the thickness. The 2.0mm Stainless Steel Blank will be 96mm to give 50mm legs and a 0.27K factor ( I use 0.27324) The 2.0mm Mild Steel Blak will be 96.6mm to give 50mm legs & 0.46 K factor ( I use 0.46425) I've been using these K factors & bend radi like this since Inventor 10 and have not had a problem.

I can get it to work if the adaptive sketch lies on a plane that is normal to the path, but not otherwise. If anyone knows how to then pattern an assembly like this down a path, please let me know.
