I see the problem this is solving and I see how it fixes the tests.
That said, I don't fully grasp how we know the IterCounts.
Given that they are in a different commit and I can assume they are accurate, I am fine with this.
As I wrote this, I realized something and left a comment below.
Otherwise, I think this looks good.
