insane: This is why people have been saying that you cannot look at speed and consistency separately, they need to be looked at together, and the 100% point for any given probe needs to be the max speed that probe has ever achieved, not the line speed.

Exactly how we do this comparison.  Cool


I think he means that effectively no provider should rate at over 100%...

I fix stuff!

If you were doing it that way, then TCL Cable would be 100%, not the 120% you are showing.

Is there a explanation of technically how you do these tests and where/what the test points are?

I can't seem to find it anywhere.

Depending on how you test/where you test to you may bias (not on purpose) a certain ISPs results.

As others have pointed above this is not how you are doing it, and the monthly graphs you create proves it.

It may work that way for ADSL, but who cares about only ADSL, the test HAS to be relevant independent of access method, and has to be bound by the same rules if you're to place the results on the same set of axis. 

I'm not knocking your effort you put into getting the test results, just start representing the data accurately or accept that others will re-create your graphs each month to tell the real story.

Ya, I agree with many of the people here.

John you know I'm a huge fan of what you're doing. But I have to say that I don't feel like TCL are being represented in the same light as others.

I agree with others, why does the graph not start at 0. Why doesn't it show just how poor TCL DSL got? Why does it cut off at 80%?

Is this the treatment that other providers can expect to get when they start delivering UFB?

If I become a UFB provider and market my 100/50 product as 80/40 and then price it at a premium, will I then show up as constantly 120% when it runs at 100/50?

Is this what this whole debate is really about? Are you thinking ahead for UFB and setting the stage for more representative marketing of products?

Are you suggesting that DSL providers should be marketing their product as 10/1 only (as that's the fault condition isn't it?) and then their services can then be more clearly and simply understood by consumers?

Again, you and everyone knows I'm a mad fan of what you've been doing, but I am left with questions about transparency at present and I don't like that feeling.

Yep Cable doesn't need a special methodology where 100% = advertised speed (rather than max measured speed).

Surely every access method (ADSL, Cable, RBI Wireless, Mobile, VDSL, UFB) should use the same methodology ie: max measured speed = 100%.

After a long delay while I crushed the numbers, here is a useful proposal for discussion, three charts that I could use for future publications.  

* A couple of notes, we do not have enough Fibre or Wireless probes for the data to be reliable.  

**The fibre speed is an average of the probes we have running, but since each probe speed is chosen from a wide range of speeds on offer, the average has little meaning apart from being close to the average of the choices our volunteers have made.

We are also only plotting 15MB/s Cable.  

Feedback welcome Laughing  PM or here

First, the same chart as before, but for ADSL only



Second, a technology chart based on maximum speed



Third, a chart to show actual speeds by technology




I have stuck to the suppressed zero.  This is for two reasons
  1. The speed is an average at each hour for a whole month and for multiple probes, it would be too hard to read if I were to show the variations about this average, but if your average speed drops to say 80% of peak, then it is very likely that the lower bounds of your speed will be in an unusable range.  
  2. Thus the impact of average speed loss is non-linear, and suggesting that average speed could drop below 50% is a nonsense, because the variation would take the lower bounds down to some "unacceptable" level (& unacceptable defined differently by each person).  i.e. how often is an unusable performance acceptable, 10% of the time? 50% of the time?  Averages cannot show this.
Comments on this choice would be interesting as well.

Some interesting data there, however I'm not sure that there's much value in comparing technologies as the limitations & relative capacities of these are fairly static and any variation tends to be due to provisioning and capacity limitations of individual ISPs.
