We analysed the results of people in Chilly-Mazarin testing broadband providers multiple times, with each test starting no more than 30 minutes after the previous speed test. On average, people in Chilly-Mazarin ran 3 internet speed tests per session. Looking at broadband download speeds, if the Chilly-Mazarin 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 broadband speed tests that don't vary by that much, we consider the final result to be the same. For Chilly-Mazarin's residents, of the internet speed tests we measured, 41.51% were fast, 20.75% slow, and 37.74% broadly the same.
