By "mil" do you mean a thou which is one thousands if an inch or are you referring to mm?
Whichever you are referring to, a fraction of 1 unit will not produce the bend you are referring to.
Your sketch shows about an inch from the parallel line which would mean about a 5degree bend and that will be very noticeable with an engineering straight edge.
I'll get the lightbox and feeler gauges out if you really do not believe me...
