One problem with following your suggestion is that you cannot refer to an older test again. By including the test id in the URL, I was able to email myself the link, make some changes to my site, then run it again and compare the new results side-by-side against the old results. If only referenced by the site URL, no such comparison would be possible. Might I therefore suggest a hybrid. Using http://www.slowcop.com/reports/www.slowcop.com http://www.slowcop.com/reports/www.slowcop.com will run the test on www.slowcop.com at the time the link is clicked, but have a way to retrieve a permalink URL to that particular test which is like: http://www.slowcop.com/reports/www.slowcop.com/4d6468ff34b95f3cbb000554 http://www.slowcop.com/reports/www.slowcop.com/4d6468ff34b95... so you can reference old tests for comparison.
