This is just my opinion:
Lets say you have two guns, the highest ranking level 10's 2.0 rate fire things you can get. We run at each other for one second, you fire three times, double shots at 0 seconds, .5 seconds and 1 second.
Now lets look at my ship...
I have two different guns, a nomad cannon and a nomad blaster...
rate of 3.03 and 4.0 times per second, my shots come at you in this order: a double shot at 0 seconds, one at .25 seconds, one at .333 seconds, one at .5 seconds, one at .666 seconds, one at .75 seconds and a double at 1 second).
I see your shots coming and can within reason easily dodge/straife out of the way. But you see my stream of shots coming and you're going to have to continuously move/dodge to avoid being hit, that alone will make you less acurate and allow me to dodge your shots even easier whilest getting more opportunity to land shots on you.
