Would be nice indeed, but that would reveal their data is flawed. In fact, I'd like to see the data per ASN and per subnet. Because you can have an ASN that spans over a huge area (e.g. all of US), where particular dense populations will show everything is fine, but more rural areas will "suffer".
In fact I used to work with a huge adult site, where there were performance metrics down to a /24 subnet level - so in cases like that, performance problems could be investigated quite easily.
