Mast Measurement

I am rebuilding my C rig masts due to carbon fibre damage and I am confused by some of the measurements and not even sure how to phrase this question!  My old style certificate has figures that don't add up in as much as A upper to lower limit marks plus G deck to lower mark does not equal (what is now called) H deck to upper mark.  It is 10 more!  The new style certificate while it has more examples for G does add up in one case but what are the other options for?

How do I use the certificate numbers to rebuild my mast?

Cheers

Trevor
