Sure... but check this out first.
Go to My Results and then change the "Days" in the top right. Filter them out instead of deleting them.
Also, looking at your results... you're testing WAY too often. You're wasting your bandwidth by doing that... and mine. 5 minute intervals are even too often in my opinion. Don't think of this tool as a consistent monitor... if you do it that way you're sending and receiving a steady stream of information. This will degrade the performance whenever the test is running.

Once every 10-15 seconds! Jiminy Cricket! In just the past 24 hours you've run over 8GB of tests. On a 50 Mbps connection that is extremely unnecessary... it also shows that you're loading the test in a way that violates the terms of use.

No worries, just a friendly reminder. Once every 5 minutes will give you a very useful amount of information without overdoing it. Just use the auto test instead.
