I know how to test it. Just take any model with a turret, make 6 firepoints for that turret that are noticeably apart, and then make a turret primary with a swarm of 6 and a 0 swarm delay and mount that weapon on the turret. Open FRED, place said ship, remove all weaponry from other turrets, give it a hostile object to fire on, open FSO, open mission, play, see results.
Speaking of testing, I got the chance to test out my modefications to the HTL Aeolus, and NO CRASHES! Of course, all the mission consisted was a hostile Aeolus (HTL) jumping in and firing on me, followed by me shooting out the turrets with trebs, knocking out the subsystems with my maxims, and then blowing the **** out of it. Now, it didn't have to face off against any cap-ships, or face off a determined assault by multiple enemies, but I think it's in a semi-useable state, and worthy of release. I actually found it harder to engage than a retail Aeolus, but then again I've never tried to take on one completely single handedly. Therefore...

I didn't include the textures to keep the filesize down, so you'll stll have to download VA's zip, but all I can say, is that that baby is gonna look sweet with alpha-shinemaps. When you fly in close, it almost looks bump-mapped. If you plan on useing it as a drop-in replacement for the standard, you're gonna have to change the filename to match the retail model, and possibly delete the LOD distances in the table entry, since it has no lods.
Enjoy!
