Similar situation. From what I can tell they have very broad areas that they know are out due to a main line. Then feeding out from the main line could be lots of streets. If those streets also have downed lines then they might not know or have those secondary streets listed until the main line is up.

That’s what happened to us. We got a text that our power was back. It wasn’t. Our street still had trees over the power lines.

Had to report the outage again and go through the waiting all over. Their restore estimates - unless your on a main line - appear to be mostly guesses.
