Resolution

This is more of a rounding issue with BlazeMeter.

Please refer to this KB article, section on Total Users:

Each of your thread groups was configured for 1.  You specified 30 users for 2 thread groups.  Each thread group will run 15 users.  You specified 2 engines.  Divide 15 by 2 and get 7.5.  Round up 7.5 to 8.  Then since you have 2 thread groups and two engines, multiply 8 x 4 and will get 32.

This is why Max Users of 32 was run.
