Hi,

While creating an excel to compare cost efficiency, it would be easier to treat metal, crystal and metal as a single number. Is 3 metal = 2 crystal = 1 deuterium a good approximation?

For comparison right now, I have cost/weapons and cost/(armor + shields).

4:2:1 would be more accurate IMO. The in game merchant also trades at those locked ratio.

Ah OK, took 3:2:1 from the production formulae. Guess 4:2:1 is because deuterium is fuel?

Yep. It's really hard to gather deut until you have your own mines set up. There aren't much fleeters around to burn it on fuel so it's easy to find people to trade with.
