As with other topics in the past, you seem prone to invalid generalizations: Just because you don’t understand the numbers, or rather, don’t seem to find them useful, does not mean that everyone else (“we”) also does not know what they mean, or does not find them useful.
I know what they mean (to me), I am fully aware of their limitations, and what they do not mean, and within that scope find them useful. And I am sure there are others for whom this is true as well.
And you probably don’t realize it now, but they will hopefully eventually be useful to you as well. As Ask made them available (or rather primarily started collecting the underlying data) to get a better insight into the “behavior” and characteristics of different zones to prepare for the future improvements to how queries are distributed between servers.
There’s also another tool to help in that respect, anyone running a public website is encouraged to embed it there.
