No, 5LDU is not accurate enough, especially for studs. Regular studs are
always spaced *exactly* 20LDU apart. The only exceptions are some very
odd, small bits. Depending on the part, studs will either be positioned on
the even-number multiples of 10 (that's 0, 20, 40, etc) or the odd-number
multiples of 10.
You should be able to position any feature within 1-2 LDU of where it
actually falls, even by estimation and rough measurement. Why? Because
standard bricks and plates contain features for which the sizes are known,
and you can use these to compare against your part.
Some examples:
LDU Feature
--- --------------------------------------------------------
4 Brick wall, stud height, height of 'foot' on slope brick
8 Plate and tile height, space between studs
12 Diameter of stud, width of technic cross-axle
16 Two plates, stacked
20 Width of 1x brick
24 Height of brick
