Edge of peg hole in 11458 too thin?

[Jaco van der Molen]

Oh yes... same issue, plate part is not really 16mm wide, but is modeled as such, and technic beam is a bit wider IRL than the modeled 9LDU diameter...

OK, then should (can) it be adjusted or is rounding an absolute must?
Maybe I will just scale the tile to make it look more close to the real thing for this particular model.
