Normally, I remove the decodes from Okha, since its duplicate of Wisonsin Point (they both share an ID). The interesting thing today is that the station went off the air, came back on, and after a bit, it must have switched IDs for a while. The graph shows this nicely.

Very interesting! I noticed a case (a week or so ago?) when I got a different number of decodes from Okha vs Wisconsin Point one night. That explains it!

I have been a fan and looking forward to the option to deep-six a station outright, but with the behavior here, I'm not so inclined to do that anymore, unless the option to remove only if could also add an option in the case of a difference of decodes is less than some number, or more strictly, not equal to another station with the same ID.
