Default Re: GURPS Ultra-Tech: Square Root of Destruction

So after a lot of number crunching, I've compiled two tables and a handful of formulas drawn from this thread and from the tables. Let me know what you think of these:

Acc = AccF x Configuration Factor
Range = RF x Dmg^2
Weight = (Dmg/BF)^3
Shots = Power Cells in AA / AA/S
ST = (5 x Weight)^(1/2) + K, K = 2 if the weapon is a Holdout Pistol, Pistol, or Heavy Pistol; otherwise, it equals 0.
Bulk is based on the weapon’s configuration.
Cost = Weight x CF

Code:
Beam Type			BF	RF	CF	AA/S	AccF
TL 9 Laser			1.5	41	1000	4.3	6
TL 10 Laser			3	20	1000	0.55	6
Rainbow Laser			3	60	1000	0.55	6
X-Ray Laser			3	1900	2000	0.55	6
Gamma Ray Laser			3	5100	3000	0.55	6
Electrolaser			2.7	10	1000	0.5	4
MAD				1	41	1000	3	6
Disruptor			2.5	10	470	1	6
Nerve Gun			2.6	2.5	2000	0.55	6
Sonic Nauseator			2.6	1	500	0.55	3
Sonic Stunner			2.6	3	500	0.55	3
Sonic Screamer			2.4	2	1000	0.55	3
Blaster				3	25	2000	1	5
Pulsar				6	6	2700	0.1	5
Flamer				3	2	500	0.55	3
TL 10 Plasma			5	2	2000	0.15	4
TL 11 Plasma			7.5	3	2000	0.06	4
Force Beamer			4	10	500	0.2	6
Graviton			1.5	8	2000	5	6
Disintegrator			60	0.5	5000	7	6
Ghost Particle			6	5	1000	0.07	5
Displacer			0.5	100*	1500	220**	6
* A displacer’s range is 100 x the radius of its area of effect.
** A displacer’s shots don’t make any sense; this figure is merely an average based on two samples.

Beam Type: The type of beam technology employed.
BF: The Beam Factor.
RF: The Range Factor.
CF: The Cost Factor.
AA/S: The number of AA cells required per shot.
AccF: The Acc of a pistol using this beam type.

Code:
Configuration		Factor	Bulk
Holdout			0.5		-1
Pistol			1		-2
Heavy Pistol		1		-2
Underbarrel		1		--
Survival/SMG		2		-3
Carbine			2		-3
Rifle			2		-4
Dinosaur/Heavy Rifle	2		-5
Cannon			3		-10
Semi-Portable		3		-8
[EDIT]
I found my formula for minimum ST for guns and launchers: ST = (5 x Weight)^(1/2) + (Moment of Velocity)/(5 x Weight). That gives the ST for a rifle. You'll have to multiply by 1.5 to get the ST requirement for a pistol.

[P.P.S]
Here's a spreadsheet that uses these tables and formulas to create UT guns of your choosing, based on the damage, RoF, and Shots. It is rough, but it's something. <Download Link>
