SWR doesn't tell you anything about pattern. It just happens to be easy to
measure, and unexplained changes in SWR tell you that something in the
Antenna system has changed, so it's a very useful diagnostic tool.

I never said the pattern changed but one can be pretty sure something is
going on, and probably it is not beneficial to antenna system. In my case, when
SWR changes it is pretty important, since the antennas lower down on the tower
also rotate. I can't have SWR bouncing all over the place as I rotate the
antenna since I don't have time to constantly retune if I switch the beam heading
during a contest. There are too many other things to worry about in a
contest.
