I don't weigh in often on the net here, but here's another point of view for static ports.
I'm a helicopter pilot and those machines tend to have a lot of turbulent, dirty rotor wash negatively affecting the static ports. To counter that we always have two interconnected ports (one on each side) and they're usually flanked by a pair of vortex generators. I'll try to attach a generic photo. I have no idea if this will do anything productive on a KR, but it would be easy enough to test before you try to relocate a static port.
