Ships & Modules

Hi there, I've been flying the Nightmare with tachyons recently doing random missions to see the damage output, which is pretty decent against em/them, but I couldn't ignore some weird behavior of the guns.

First the fit:

Lows:

x4 Imperial Navy Heat Sinks
x1 Tracking Enhancer T2

Meds:

x2 Shadow Serpentis Tracking Computers (+tracking speed)
The rest are just tank modules

High:
x4 Tachyon
x1 Drone Link Aug.
x1 Small Tractor Beam


Tracking Speed:

Amarr/Caldari BS = V
Support = V

=>0.046 rad/sec


Weird Behavior:

1. I have my weapons split in 2 groups of 2 in order to avoid (as much as you can) overkill.
2. Every time i activate them both, shooting at the same target I will get the following:

a) 1 Group hits for " " well aimed damage whilst the 2 Group hits for " " lightly - This happens the most frequently
b) 1 Group hits for " " excellent damage whilst the 2 Group hits for " " barely scratching - This happens frequently
c) 1 Group hits for " " well aimed damage whilst the 2 Group hits for " " hit - This happens frequently

I have yet to see both groups hitting with the same modifier excellent or Well aimed. Perfect is totally missing, doesn't matter if I am hitting big structures or battle ships (both 0km transverse). Anyway, the point I am trying to make is, that when one group hits with higher damage modifier ( modifier > (normal)hit), then the second group will, guaranteed, hit with a lower damage modifier ( modifier < (normal)hit), regardless the transverse speed of the target. This pattern keeps happening every time I shoot at things.

Anyone else experiencing the same?
Is this normal behavior and I am just a random noob?
Will Robin be able to prove his endless love to Batman?

Thanks

It becomes pretty much random, for both sides, lower and higher modifier, the problem there, is i cant not identify them well enough.
