How to apply bend compensation in flat pattern

Hi there,

I'm working on a metalsheet project with a 20mm bend radius which is bend in an angle:

The only problem is that the real life prototype is not quite as neat as the sw model.

I'm experiencing 2 problems:

1) Quite a big shift/gap:

2) Corner is not nicely curved (maybe this has to do with the punching machine instead of laser cutting the flat pattern)

Does anyone have a suggestion how to solve either of the 2 problems? Obviously I could try to add a bit of extra material on one side and extract on the other side in the flat-pattern, but this feels like a last resort solution for problem 1.

Thanks in advance!
