I think I am just asking the question wrong.

The base question is this: Is there a way I can determine the relative value of things across tech levels? I am looking both for GDP ratios and for combat "potential" ratios.

In the case of GDP, how much more effective is 1 billion TL F workers than 1 billion TL D workers? (Or for other TL comparisons?) Yes, there are some charts on this in TCS and in GT:FT. Unfortunately, TCS includes starport in the deal, and just assumes a 5% difference per TL/starport class. GT:FT would probably be useful if they would have given a quick sidebar on TTL ratios instead of just GTL ratios.

In the case of ships, how much more effective is 1,000,000 dtons of TL F combat ships than 1,000,000 dtons of TL D combat ships? (Again, going through all the TL comparisons.) I have never really seen this addressed anywhere.

To show where I am going with this, let's assume there are three interstellar polities. I will express their size in billions of people (i.e. "workers") at given TLs. Assume their navies are directly proportional to their populations.

IP1: 18B pop at TL F, 8B pop at TL E

IP2: 8B pop at TL F, 18B pop at TL E

IP3: 9B pop at TL F, 3B pop at TL E

If IP1 and IP2 face off, how much of a disadvantage is IP2 at? Is it a slam dunk, or is still close enough to give IP1 pause to think?

I figure

*someone* out there has less of a life than I do and has already given this some thought.
