That wouldn't be how I would use that data, unless we had a mandate to maintain a given PF for financial reasons. Some power suppliers impose a penalty and there are other cost implications. The ratio will typically bounce around as different loads are switched on and off so detecting a problem that way would require that you know a lot about what's going on. So you might use it to justify PF correction gear. But since it is almost entirely dependent on the loads connected, it is generally something you live with, or correct to the extent that the variation allows.
