I have also noticed that BEE curation went down significantly... It was over 100%, and now it's under 70%... For that reason, I have split my BEE tokens among curation and diesel pools...
I suppose that more people are staking BEE tokens, and that's why the APR on curation went down... You can check numbers about tokens here https://leodex.io/token/BEE
