There are quite a few things in the CRL which aren't completely accurate, but these things are and do get pointed out to people on their build journey, ie: like the belt if you trim the corners of the front plastic section correctly you would see that you end up with approx 75mm between the corners which should be the width of the belt, looks weird if your belt is bigger than the front plastic piece. The arguement is yes it would be easier to list all of the exact measurements and requirements but building your armor is a learning curve and I think that like putting in the extra work for EIB and centruion, learning all of these exact little quirks although annoying can be rewarding in the end, you know how hard it was to get there but it was well worth it in the end.
On a side note some are building to requirements that are not even in the CRL for EIB and Centruion, it all boils down to research and how far you are prepared to go on your building journey.
