If you can get phd to guide, you dont use the bullseye. After it does its calibration PHD knows how the camera is orientated and therefor which way any movement of a star is.
What I do if I cant use alignmaster ( which is also very good ) is calibrate phd on a star at the meridian and celestial equator (pointed up) then when it starts guiding stop it. Opening up the brain window with all the settings there is a tick box that says Disable guide output. Tick this and then the program will watch the star but not make any corrections for its drift. Thats what you want. Then you can start "guiding" again, and open the graphs. Make sure they are set to RA/Dec and not Dx/Dy. I think you can do it with the derivative graph but I find it easyer with RA/Dec. Then all you need to do is watch the RED line only, It will move from the starting point usually fairly quickly and you can then stop the guiding and make an adjustment to the azimuth bolts. All I do when im doing it is do large adjustments first to make the graph drift less or even better in the opposite dirrection, and then fine tune the bolts.
This obviously needs repeating on a star low in the sky for altitude, but I can generally get good alignment relatively quickly as you can see the drift happen instantly with phd's sub pixel accuracy.
