I don't see these as particularly bad numbers. The total number of votes went down, that is logical as each vote is worth more. People are being more selective on what to upvote. That makes for better curation.

The number of Authors increased by 80% That is awesome! The heart of every social media platform is the diversity and amount of content. This is huge! A big win.

And as intended, the number of votes per account had decreased by 32%! Perfect, as whales were over-voting while everyday users were under-voting. So it is likely those whales reduced their number of votes while regular users remained the same. (my assumption there)
