+## Time categories and totals
+1. TestTime - spent on executing configuration or test case functions
+2. FrameworkTime - e.g. spent on executing hooks
+3. ElapsedTime - start/stop timestamp difference for test execution

+### sequential execution
+Without parallel execution ElapsedTime would be close to sum of test and framework execution times.

+> ElapsedTime ~= FrameworkTime + TestTime = (F1 + F2 + F3 + F4) + (T1 + _T2 + T3_ +T4)
+
+### parallel execution
+With parallel execution ElapsedTime is expected to be smaller than sum of test and framework execution times.

 ## Problem (GH-7119, OTP-11894, OTP-14480)
 I think the most confusing thing is that today OTP behavior and design seems to be a mix of Configuration and Testcase centric attributes:
 1. (Configuration centric) CT hook callback looks as designed to wrap around CT Configuration functions (i.e. you have *pre* and *post* to wrapp around init_per_testcase or end_per_testcase)
