 In the left chart, orange denotes all ISPs whose actual speeds were below their advertised speeds. In the right chart, orange denotes ISPs using DSL technology.

It's the same, DSL is the only tech with actual percent < 100.

Thanks David. That would be their logic. If I were doing separate charts, I'd have selected different color schemes.

@David - that was my initial thought, but it is not the case (as far as I can tell).

Charter is a cable company, Frontier Fiber is surely a fiber company, and they both have values below 100%.

I think TWC is a cable company as well.

I really like your version. it seems like the DSL category should be at the bottom though so the groups are in rank order like the subgroups. great analysis.

Mike: You'd be right (see my critique of my own chart below the chart!)

@jlbriggs: values under 100% are orange, values oevr 100% are blue. Thgat's true for the left-hand (ISP) graph and the right-hand (technology) graph.

"Charter is a cable company, Frontier Fiber is surely a fiber company, and they both have values below 100%."
The fact that some ISPs have values below 100%, even though the average for their technology is over 100% has nothing to do with it!

As a consumer I would actually be more concerned with actual speed instead of the ratio between advertised/actual. If the ratio is 90%, but the speed is twice as fast as someone whose ratio is 150%, I would rather go with the provider with the worse ratio.

jlbriggs

@Tom - yes, I got all of that.

My post was in response to the assertion (made above) that orange was for DSL and blue was for the other types, in both charts, and was not in regard to whether individual companies differed from the average of their type.

jlbriggs

@henry - but it's a matter of advertised vs real, not who is fastest.

What is advertised is advertised as a certain speed for a certain price, so it's not a clear matter of "faster wins" (depends what you want to spend), and there is no inherent suggestion that a consumer should buy from whoever has a better ratio.

It's a matter of what you can expect your actual speed to be when you buy a certain advertised speed. It's a tool that can be used to assess whether switching your ISP will get you what the ISP claims it will or not, for example.
