Re: So what is the average internet speed?

[Rich Rubasch] "I doubt most internet connections in and around Madison WI USA are over 5 meg download and 1 meg upload."

And I think the aforementioned site may overstate real averages. The ones motivated to run the tests are those who are speed conscious. Typically viewers may not have any idea their ISP isn't even close to promised speed and will often think the issue is with the file. It's best to error on the side of caution.

[Rich Rubasch] "At work we have 25 meg download and 4 meg upload through Charter cable."

I have 32mbps down and 5mbps up and I'm only on a "mid tier" for my provider. I get my rated speed. On the other hand I know people that are on the same tier and get less than 1/4 of the speed and may not even be aware they have a problem.

Also there's also the "household" issue. If a couple other people are using bandwidth at the same time a household with 3 people online and 5mbps may be very much divided.

I think your approach is wisely cautious.
