You are fortunate that tou hand laid your track. Di Voss, the standards chair, has been testing all the manufactured turnouts and NONE meet the standards. He has realized that the system in general often specifies minimum and maximum dimensions where the manufacturer chooses that number as his target and manufacturing tolerances cause variations. He is currently working on revisions stating a firm dimension with +- tolerances to make compliance more likely.

But, like axle lengths etc., the dies are in place and not likely to change soon.
