Perseid meteors are seen all over the sky. The higher the radiant is, the more of the meteors will be seen. That's why the best rates are after midnight when Perseus is higher in the sky.
The best place to look is a bit higher than halfway up in the sky, in whatever direction it is the darkest/clearest/least light pollution.
The ZHR is calculated for very dark skies (technically, limiting stellar magnitude +6.5...i.e. a very dark mountain site far away from city lights) with the radiant at the zenith (directly overhead). Since these conditions rarely occur, the observed rate will almost always be lower than the ZHR. For example, for me the radiant reaches a maximum elevation of 75 degrees, but that's at 6 AM when the sky is quite light. And my very best LM is about +6.0 on maybe 3 nights a year... normally good nights are ~ LM +5.5, which knocks out about 40% of the meteors from the Perseids, because the sky is brighter than the meteors.
