For this kind of calculations it is better to use median than average...
average can easily get substantially biased in both directions by a few
"odd" requests.
Also, the average response time depends a fair bit on your setting of
half_closed_clients..
For example, 0.1% of stalled requests with "half_closed_clients on" will
add almost a second to the average response time.
If you cannot do median, then atleast add a filter to your calculations to
ignore requests with a very low or high average thruput as these are are
mainly slow because of other criterias than your link or proxy.

You can only compare measurements done in the same manner with similar
conditions.
How is the "dialup-line" measurements you are comparing with performed?
