Well you need to be marking to adjust the state vector after confirming a good lock on. I will try to outline this as best I can without showing you....
-While in P00, RR SLEW, slew up and down until you peak the signal strength (should be about 2.2 or so)
-Switch RR to AUTO TRACK, make sure it gets a good lock on and the signal strength meter stays high
-Maneuver the LM to center the RR needles as best you can (this boresights the CSM)
-Run P20, bypass auto maneuver, and when you get a 201, switch from AUTO TRACK to LGC and hit PRO
This should let the LGC lock the CSM properly. Once you have confirmed a good lock, type V80 to begin marking. You will get a few small state vector adjustments. Also you need to be constantly moving the LM to keep the RR needles mostly centered so you dont go >3 degrees beyond LOS.
Just don't really like screen streaming type of thing.
To each their own I suppose, it does help tremendously with this sort of thing.
