That is by design. Could you please let me know why you don't want the think time to be included in the response time for the test?
Only because it detracts from focusing on the viz performance.
Depends I guess whether you are focusing on user journey or viz performance.
It’s a moot point really as I’ve come down on the side of not using a think time anyway.
I’ve also spotted that it is broken out in the Test Drill Down dash board in the PerformanceViz.
