One other consideration is that if you're
aiming via a "meter" rather than the readout on the receiver, generally a signal meter won't allow you to peak polarity, because when you turn the feed, as you are peaking one polarity, the other polarity is getting worse, so it pretty much stays constant. Ie to peak polarity you almost have to be using your receiver tuned to a transponder of a specific polarity. But polarity isn't that critical, so if you start from vertical, and rotate via the
Sadoun calculator, then yes, you should be fine.
