Hi
Am with Colin on this. At 100% aggressiveness you are bouncing around. In good seeing it should be no more than 50 to 70 %. If you focus just on RA, you can see from the graph that you are over correcting.
The intent is to make as few corrections as possible so you need to drop your aggressiveness. Also worth upping your guide exposure settings unless you managed to sneak in AO as part of your sponsorship?
Have a look at the resources under ccdWare.com to get some hints on guide settings . Resources, auto guided settings calculator
