Turret range issue

OK, the only use I want from this is the turret range. I have no interest in the others, possible flame turret range but that's still being debated. 

Anyways, the issue is, default range is 30, so it will target you on 30 or less & shot until you move 31 or more away. But if you extend to 35. It won't shoot you at 35,-31. But it will keep shotting you from 30 to 35. So the extra range only comes into effect if you enter it's default range & you run away. 

I was hoping this plugin would allow me to extend the detection range of turrets. 

i Have found that it will return fire from someone as far away as 250m , I have my range set to 300 and no one has got to any base i have built (on an iceberg)  or managed to pass close to the base in a boat/swimming.  It will probably ignore players who pass by at over the 35m range but i have not got that close to anyones base without taking the turrets out first.
