I have implemented a system of unit stats that makes it more complicated how damage is dealt, but more true to FS, in my opinion.
Here is a table of all of the different ships, their HP, and the average amount of damage they will do per attack to the target (targets are in the same order as attackers):
Perseus Squadron (360) 199.5 199.5 133.5 199.5 265.5 265.5 265.5 265.5 133.5 133.5 133.5 133.5 133.5 133.5 199.5 133.5

Edit: As an alternative (the file used for this is incompatible with the released version, but it is compatible with the next version, if I don't make any major changes), this table, in which capital ships take higher damage from all attacks:

Suggestions needed for how to properly balance. For example, a Colossus, IMO, should be in between these two, it shouldn't be able to take a Colossus down in one turn (three attacks), although a Sathanas (will come later) should be able to do it in maybe two turns.
Edit: These tables have both been replaced by a new set of "damage modifier expressions," and there are now three tables, all viewable in the (unreleased) "Other Options" menu.

This last one is the "ultimate" one (as far as data type, not the info that went into it) that all the expressions should be modified to suit. I can see already that it is majorly unbalanced, and I would like suggestions for how to balance it. Other tables are important to a degree, particularly the second one (a better analysis of the first). The first table also can be used just to make sure that, for example, all bombs do more damage than lasers.
