yes

I was seeing something else, and I don't have a url. I think that what
I was seeing is what they use to make the arewefastyet.com site.

I don't think you understand what I want. Sorry if I was unclear.
I am fine with the way that the benchmarks are displayed right now,
but I want a way to dynamically do there and say, I want to throw
away all data that is higher than a certain figure, or lower than
a certain one, because right now I am onoy interested in results
in a certain range.

I'm not looking to change what the benchmark says for everybody
who looks at it, or change how it is presented in general.  I just
want a way to zoom in and only see results in the range that 
interests me.  You and anybody else might have a different
range that interests you, and you should be free to get this as well.

The problem is that I want to throw away arbitrary amounts of data
regardless of whether they are statistically significant or not,
on the basis of I know what I want to see, and this other stuff
is getting in the way or being distractingÃ.
