Getting familiar with the Athlon MIL reticle

Hello,

I always learn my reticles all dimensions (Not an owner yet, but I will be)

But I had to contact Athlon because I could not get a grab of their reticle documentation.

Here is the link to FFP MIL reticle (Used in Argos line at least)

See page 5.

If you would mind to check what these values are about? Some are seeingly bigger than the given value.
A2
A3
A4
C1

Thoughts?
 
The diagram may not be to scale, which may cause C1 to appear incorrect. A3 and A4 though definitely look questionable to me, flipped at least...? Never have understood why scope manufacturers feel they need to divide 2 adjoining mil units into .2 mil, instead of just 1 mil unit.

If a couple of the specs are incorrect (not saying it actually is), it wouldn't be the 1st time I've seen it happen.
