it would be great to see the percentages of PR

Accepted denied percentage for periods of time.

Our complaint is most of the things gets approved and we can not measure that.

It sounds like you're looking for some kind of reporting tool that can give you a historical view of PRs that have already been closed. That falls outside of the scope of what this extension is trying to accomplish, which is to give a useful display of current in progress pull requests. This is not a feature that fits for this extension.
