Attention:

SleepStudy uses 15 minutes as the statistical interval. If your test is less than 15 minutes, the test results may not appear in the report.

If there are a large number of event records in your system (for example, the machine performed a Restart or Shutdown Loop est before), the resulting export may be very slow, and it looks like the program is stuck. 

Please be patient at this time. In other words, if you want to check the MS status of the system through SleepStudy, it is best to find a "clean" system to test.

There is no way to clear the SleepStudy Log. If you know, you may wish to write it in the message and share it with you, thank you.
