I would imagine everything depends on the provider and region as you are already aware.
 
As far as a page to search <my town or city> & <results>  have you used https://testmy.net/list ?
 
Search for the town and go from there. Sure it takes a bit of 'footwork' to get the data extracted the way we want to see it. Though if I'm gathering mental data correctly, we should be seeing new features soon here at testmy.net.

The same logic where more people are likely to post negative reviews than positive ones.  You're probably right, to a degree.  I think there are also plenty of people who test here on sunny days.  If that is true, it's true across the board with all providers.  They're all being judged using the same method.  In my experience, the better providers always perform better and rank higher here.  Is any of this perfect, no.  Will it ever be perfect, no.  Will I try, definitely.
 
After TMN's recent full switch to https (SSL) settles in with the search engines I have an upgrade to the host stats pages you mention.  It aggregates a much broader range and I think it better represents the highlighted ISP, city or country's speed because it won't just be showing you the logs like it does today.  It will unlock a huge amount of information that TMN has been calculating and storing in private databases for a very long time now.    So look for that tool to become higher resolution in the near future.

Again, as a newbie, I ask what is probably a dumb question:
 
Isn't the speed data on any given ISP (in my case, V-Media, https://testmy.net/hoststats/vmedia#, likely to be skewed toward unfavourable results if (maybe I'm wrong about) the graph on that page shows the results of the "last 50" test, given that tests are MOST OFTEN performed when the performance of a particular ISP are "shite"?
 
I MIGHT be mistaken.......I have been......a couple of other times!
