I'm experimenting on revision history dumps of Wikipedia.
Do you mean the English Wikipedia?
I've confusion regarding archiving of Portal:Current Events in revision history dumps.
The title you mention only has 2 edits: https://en.wikipedia.org/w/index.php?title=Portal:Current_Events&action=... The target page has 2100 edits: https://en.wikipedia.org/w/index.php?title=Portal:Current_events&action=...
Do you expect more? Note that of course most activity happens in the transcluded pages: https://en.wikipedia.org/w/index.php?title=Portal:Current_events&action=...
