What is the Fair Usage policy, with respect to BrowserStack Automate plans?

Certain Automate plans are subject to fair usage, which is a time limit set on daily use. The limit varies depending on plans:

Lite: 4 hours per day
Basic: 8 hours per day
Rapid: 20 hours per day
Rapid Plus: 40 hours per day

Automate plans are divided into parallel tests, and the time limit applies to the cumulative testing time of those parallel tests. That means the testing time is calculated individually for each parallel test, even if they are run simultaneously.
