We've just updated our test suite. We've not been able to collect reliable scores of some older browsers
yet. As more results come in we will add the remaining old scores. This will probably take a couple of days.
The data above is compiled from automatically submitted test results. It is possible your results
may differ slightly due to external factors such as settings and which operating system is used.
If you believe the data above is incorrect, or if you think we are missing an important browser
or device, please open a bug report at Github.
