It'd be interesting to see results if you added in advanced turret gyros (or dropped optics, or even both); remember, optics reduces turn speed.
Repeated 3 times, hullmods were Gyros, ITU and Optics, the Medusa did not move
Burst PD: 12-14s
PD: 20-22s
Tactical Laser: 19-26s
LRPD:23-32s
Burst PD with expanded magazines: 9-11 (only proxy charges are faster)
A clear improvement, turret turn speed has definitely more effect for fighter defense then I had anticipated.
To test this further I let the relevant hullmods compete, gyros vs. optics:
The results were weapon dependent:
With TacLaser:
Gyros: 21-23s
Optics: 1:46min!
With PD:
Gyros: 25-31s
Optics: 19-22s
So there is no clear winner, it seems to be best to try and compensate a weapons weakness with hullmods.
Well, the tests were performed with Talons, which are fast and have to come very close, so the turn speed had the advantage. But definitely don't combine TacLasers with only Optics if you want them to kill fighters.
do the test again, but this time move the medusa forward.
Doesn't make much difference, a little slower since the Medusa has 3 back- and 4 forward-facing turrets.
