Comments on JET’s weapons formulas

I’m trying to work out which is the most effetive weapon:
First thing I notice is that (using Jet’s formulas on this site) is that anything with 100 armour more than a weapon’s penetration will not be touched by that weapon. This implies that the armour of all ships must be less than 150 otherwise a PBC wouldn’t scratch it.

If you then calculate the damage rate, the Quad Lite comes miles out on top for all armour <~130. For instance: against armour 50 at a range of 1.2km, Quad 733 hp/sec Rapid PBC 533 PBC 229 Assault 1067 Heavy 208 Neutron 333 Antimatter 467 Gattling 1333 Only at ranges > 2km does the Quad fall short of the rapid PBC, but it’s still twice as effective as PBC/Cyro/targetter/wide/pulse against all armours <~130. Since I always fire at max weapon energy this equates to 3km. This doesn't seem right.... any comments?
