nice stats and good results.
I want to point out though that "
Errors: Inner rings with same tags as outer rings"

are not necessarily errors, and should not be "fixed" unless you know very well the situation and can tell that there's indeed a redundancy/data problem. E.g. you can have a building or building:part inside another building or building:part. These could be tagged still "incompletely" hence having just the same tags for the moment but be different objects nonetheless. Similarly woods inside woods, etc.
