@carref43 , I've added a graph of all tests taken from you connection ID logged in or not.
I see you've just recently joined however. Make sure you are logged in while testing.
Nice, steady test results by the way
No testmy.net does not require a static IP to log results, however members have their own database. Since you were likely not a member since running the tests you did, therefore not logged in, the tests are not saved in your database.
There could possible be means to recover older results, @CA3LE would be the guy to discuss this with.
