I’ve noticed that the “Top Identifiers” section in observation updates live, and the leaderboard on the taxon page updates less frequently. That would explain the different between 2 and 79. But that doesn’t explain why they can show 3 separate values.
Sometimes the difference between values can be more than 100 IDs, too.
That’s interesting. I wonder why they are all displayed in different ways. I think it would make more sense to have only one. Or, have all 3 but explain what they mean. For example, a Live section, one that updates daily, one that includes withdrawn IDs, etc.
