User:Evil4Zerggin/DPS efficiency

Lasers
One pump plus 0.25 of a cavity costs 887.5 RP, or 250 metal + scrap. Production is 50 laser energy per second, which could do 100 damage with a 4Q laser. So DPS per kRP is at most about 110. About 400 DPS per metal + scrap.

Missiles
If we figure 10 blocks required per pad, that's 1k RP, or 300 metal + scrap. Supposing 25% payload and 1.5k net damage per payload block, we predict about 100 DPS per kRP, or 333 per metal + scrap.

Cannon
The "Catspaw" deals over 2k DPS and costs 11k RP. That's about 200 DPS per kRP---if we hit. Also it's been nerfed in devtest.

CRAM Cannon
An HE CRAM deals about 16k explosive damage every 18s and costs about 100k RP, or 30k metal + scrap. That's about 10 DPS per kRP, times explosive splash factor and armour, perhaps about 3?

Particle Cannon
With a full loop and default stats, one 400 RP (150 metal + scrap) pipe produces 100 DPS. That's 250 DPS per kRP.
