Sloped Minifig Leg 3817b is wrong

[Philippe Hurbain]

The only big issue is the pirate leg. How should it be changed to match the new position of the foot?

I checked LDraw model of 2532 pirate leg against 2532 model from Unity microgame, they match perfectly so pirate leg is fully symmetrical in Z direction. This makes sense to use it for left or right leg! (Though it seems to be used only for right leg in existing minifigs).

Or is that difference explained in another way?

LEGO solves this by modeling the stud hole as a rectangle (screenshot showing LDraw 2532 + leg model from catalog app)!!! (4.99mm x 5.45mm)
But IRL I measure a perfect square of 4.8mm. So I guess that a pirate is very slightly rotated (or flexibility everywhere does the trick!)
