A mod for Length in Rec Manual?

Hello, it's me bothering again

I noticed that Recognition Manual in SH4 doesn't have the length of the ships, and I miss it a lot because in SH3 I loved to calculate ship speed using the length and the chronometer.

I was wondering why? I mean, the lack of the length is a realism feature? true manuals didn't have the ship length neither?

Also, I was wondering if there are mods that adds the length to the manual, I found this:

But both of them have broken links. I would appreciate it if someone can suggest me a length mod.

Thank you in advance and sorry for my bad english
