I just ran across this power priority data listed in the OP API, and can't believe I hadn't noticed it before.
I'm not sure how (or even if) these numbers are really used of course, so take them with a grain of salt, but it's interesting to see the numbers none-the-less.
Code:
70: Cloak
60: Phaser G, Shields
55: Phaser 3
50: Phaser 1, 2, 4, X
45: HeavyPhoton, DIstruptors
39: Plasma F
35: Plasma G
31: Fusion
30: Photon, Plasma S, PPD, ESG, Phaser A/B, TRB,
25: Hellbore, Plasma R, I, D, X, E
20: Mauler, Shuttles, Fighters, Drones, Probes, ADD, Labs, Sensors, Scanners,Transporters
10: Battery
EDIT: needless to say, I'm going to have a play with this and see if changing them has any impact
