I don't have any data to back this up, but I'd be incredibly surprised if it was something more than "each unit has a "pointy stick value". Add up the "pointy stick value" of all units you own".
That said, you could achieve your personal experience quite easily if the relative "pointy stick value" of a more technologically powerful unit isn't the same ratio as the increase in combat effectiveness.
There might be more concrete evidence in the XML, I'll see what more I can find.
Multiple editions of Civlization 5 have been released.
Some as retail boxed versions, others as digital downloads.
The premium editions contain bonuses which range from:
- metalic figurines
- art work
- music tracks
- behind the scenes videos
- extra civilizations
- map packs
- posters / misc. memorabilia
Many retail stores provided different or unique perks included in the list above, so it is difficult to give a full list. Also it is not possible to buy a supreme version with all the perks listed above.
Note that There is no hard copy manual released with any versions of Civlization 5, further more there are no hard copies of the technology tree.

We’ve made the formerly 200+ page printed manual an improved interactive PDF. This PDF manual allows you to click on screenshots to see them clearer than thumbnails, navigate much easier with clickable links, and most importantly, look forward to manual updates as we make changes to the game. But don’t take my word for it; I have a sample of the manual for you to check out: Click here to see the sample. Included in the retail copies is a small quick-start manual to get you up and running as quickly as possible.
The last sentence references a small pamphlet included in retail copies, but not the full manual.
What you may have seen on youtube was the Collectors edition artwork book
This is not the manual, but a picture book containing artwork related to the game.
As far as I know, this edition was only produced as a once only batch when the game was released and it is quite difficult to find copies for sale.

The mouseover for your own score helpfully shows from which categories how much of your score originates.
I've experimented a bit and my preliminary composition of the score is the following:
These results are from the start of a game, I assume they don't change but I can't be sure yet. It seems some things count for fractions of a point, so the numbers here may be rounded. The numbers also seem to be always rounded down, not to the nearest number.
Units and Gold do not seem to have any effect on the score.
Wonders count for a lot at 40 point per wonder. But also new cities (at standard map size) result in 19 points (10 for the city, 3 for 1 population and 6 for the land). Technology seems to be rated pretty low at 4 points, you have to research 5 technologies to get more points than one new city.
