Modding Help Trying to sortout the "statusEffectArea"

I'm trying to edit the area of effect of the Lowgravzone, and run into this(at lowgravzone.projectile): "statusEffectArea" : [ [-6.0, 0], [-4.0, -4.0], [0, -6.0], [4.0, -4.0], [6.0, 0], [4.0, 4.0], [0, 6.0], [-4.0, 4.0] ],
I want to know how to grow the area of effect, I imagine that these values are cordenates. But no change that I've made seems to have much effect, for example: I've doubled the values but it didn't had any effect.
