The thing about RSO radar was it used 4 times as much electricity, in addition to providing 4 times as much coverage. This mod gives the coverage without the electricity increase. It's a straight buff (and a pretty big one) without any mitigating downsides.
I'm assuming you were attempting to avoid doing what RSO radar had to do to increase the drain, by redeclaring all the variables, but it's the only way.
Perhaps you could increase the amount of energy to scan a sector?
