When a new Challenge cache is published (with a checker of course) the green and red stat bars on the checker image link show zero and zero, and these count up in line with what checks are made.
The only link download I can find is the sixth option under the USE CHECKER link on the right hand side of the Challenge Checkers page, but this downloads a link already populated with erroneous stats.
So if it's not possible to reset stats to zero within that link, where do I download an HTML link for a checker image which is already set at zero zero?
When a checker is first created, the stats are 0 and 0. Then the checker is tested by the tagger, owner and reviewer. The stats from these tests are what would be visible when the challenge is published.
