Add Percentage of Changed Reviewers for Each Iteration

[dnozza]

It would be interesting to see the percentage of new reviewers that replaced the previous ones for each iteration step.

@dnozza I agree, this would be interesting to report. I will add these statistics to the iteration pages. Thank you for the suggestion! :)

Great Suggestion!
I was just going to suggest this too, just because I participate in multiple rounds of ARR as a reviewer, but in each round, there is no paper I have reviewed assigned to me. And I always review papers that have previously not been reviewed by me. This makes me worried if there are too many duplicated jobs for these resubmitted papers. But if there will be such statistics to be displayed, I will know if this is a special case or a common case. Many thanks!
