[Guide] Player Owned Base

[UK1]

OK I have a rather interesting problem which some of you people might be able to help me with....
Is there some kind of secret level or amount of weapon platforms a base can support per base core level.
I ask because I have a base which is level 3 which has 5 weapon platforms and they don't seem to work properly...
Then again I also have a core 4 base with 6 weapon platforms which the base defenses work great...
All the plaforms have been positioned dead close to the station just far enough away that the distance counter just about starts to count kilomitores if I was to move just a little futher away...
Now on the second base at core four which the weapon platforms are positioned the same they all work great.
But on the core 3 base they really suck...
So I'm wondering is there some kind of secret limit on how many weapon platforms a base will properly support per each core level and if you exceed that amount the affectiveness drops to a really poor level...??????????
