Humm...look at ZWO's own data, the PE does seem to be about 30 arc sec. Might be high frequency ripple there too of about 1-2 arc sec....
But, it's Christmas so..." Everything is awesome. Everything is cool when you're part of a (zwo) team "
P.S. My decade plus old-school Losmandy Starlapse has +/- 6 arc seconds of PE.....might keep it a bit longer
