Thanks for the feedback. Yes, that's how the calculation is done internally. However, it is easier to explain the concept of approval rate if broken up separately. We are seeing a lot of curators still submitting indiscriminately - it's important that curators understand that quality and approval rate is top priority.

The actual formula used is -

(Number of posts approved)^2 / (Number of posts submitted - number of posts closed)

[Sometimes we "close" posts without either approving or disapproving if they largely meet the guidelines, but we can't vote on. E.g. posts that had less than $1 pending payout with the curator submitted, but went over by the time it was reviewed. These submissions shouldn't be penalized even if we don't vote on them]
