Missiles are very different from turret.
The main reason, is that the application formula is linear with the evasion and not exponential.
The second reason, is that the signature ratio can compensate the speed ratio, but not the opposite. so if I use a 110 m/s missiles against a target going 165 m/s, using one web will reduce the target speed below the missile explosion speed, and thus multiply the application by ±1.5 , even if the target sig is much lower than the explosion sig ; on the other hand one faction painter on the golem would multiply the application by 1.62 , up to 1.
Then if you use rigs like calefaction II + flare II the speed is even less an issue,so painter is better (because the speed reduction is lower)
