Ratings making me sad - they have dropped because of the challenge

I’m not sure if everyone understood me, so I decided to create a screen recording showing the total count of nominations reviewed before and after an edit: plus1.mp4 - Google Drive

You’ll see my total was 5831 before, with an additional one after the edit. Has it always been like this?

I’ve done many reviews since the challenge, hoping to improve my rating after I dropped during the challenge. However, if this only worsens my ratio of agreements, I’m worried I might be doing the wrong thing by continuing with these reviews right now.
