I had missed a couple of the app_config edits to use the correct gui_rpc_port and ended up missing hours.

If I didn't have the correct qui rpc port I wouldn't think I would even get any Wu's to the client ???

They run the full 6 hours but I think return invalid or inconclusive. I fixed them some time ago so I don't have any to check now.

No factorization on any clients?

I've only had 1 Wu that erred out this year on June 5'th it looks like, the no response ones are clients that I shut down for the summer month's because of the heat:
