Regarding the front end- I'm looking at the template as if I was going to build a car from scratch. I may try to model it using CAD software.

It seems there would've been text instructions to go along with the diagram in the original source.
The original source is Aerohead, he has compiled a vast knowledge through his studies and practical experience in the field.
It is a composite fulfilling a number of aero guidelines and as he has said it is a quick and safe guide to build a boattail that works, it's not the only shape and maybe not even the best, but it is tested and it works.

If you look back a few pages, 4, 5, 6? I was looking for the original source and an equation so I could easily produce dimensions, the best I came up with was the NACA 0039 airfoil, very close to template, but not exactly the same.

There really is no such thing as concise when you want to know how and why something works, because concise is not complete, so you still end up asking all the questions to get to a complete understanding.

If you want to do some serious aero work, you will need to gain a complete understanding of the template form, even if you do not use it in the end, you will still need to understand it fully so that you can make informed decisions in your design process.

Short cuts always take longer in the end.
