Accurate speed tests

This is an overview of accurate speed tests. That is, the speed tests are displayed on the descending -average- accuracy score as determined by the standardized speed test. The accuracy score is listed in brackets after the speed test.

The average accuracy score

We know that which speed test is most accurate depends on the speed test you measure.

Hence we calculate the average accuracy score for each speed test.

We consider a speed test as accurate when the accuracy score is above the 90.

The order of this list will be different when you have one specific speed in mind.

Tested with one speed

The following speed tests weren't tested often because they weren't initially considered interesting enough. This could be because the speed test is a clone, the initial score wasn't great, or because the speed test isn't popular and has been demonstrably inaccurate at a specific speed.

Therefore, too much significance should not be attached to this list. For a specific speed it is better to inspect our page: The most accurate speed test.
