How do I best manage my health and damage boosts during construction?

Here what I know:

When you add more weapons of the same type your fire rate increases, which thereby increases both damage and drain per second. The firing rate boost is capped at a certain point for each weapon, im not entirely sure but some may not get a fire rate boost when theres multiple though I believe they all do at least a little. Your "Sweet Spot" is where you want it to be. If you prefer burst damage, add more guns until you seem to hit the fire rate cap. If you prefer lower damaged sustain, keep your gun count low. If you want high damage AND sustain, build a small robot with a big damage boost and only a couple low energy draw weapons. As for speed, work it in where you want. Its really a rock paper scissors type deal where as you add more of one your potential for the other two slowly decreases.
