Karlsruhe Speed Test Results

We analysed the results of people in Karlsruhe test providers multiple times, with each test starting no more than 30 minutes after the previous speed test. On average, people in Karlsruhe ran 4 speed tests per session. Looking at download speeds, if the Karlsruhe resident's final test is 10% faster than their starting download speed, we count that as a succesful and faster speed test result. We count an unsuccessful, slower result if the final result is 10% slower than the starting result; we'd hope their ISP contacts them ASAP! For speed tests that don't vary by that much, we consider the final result to be the same. For Karlsruhe's residents, of the speed tests we measured, 40.48% were fast, 23.02% slow, and 36.51% broadly the same.
