JMeter - Throughput Shaping Timer - How does it work?

This is my test plan

enter image description here

I have only debug sampler. 5 concurrent users for each thread group. Ramp up 1 second for all.

So overall 20 users - ramped up in 1 seconds.

Debug sampler throughput can go more than 100000/sec. As you see, no other timers except Througput shaping timer.

Issue: If i run the test, I was expecting the min throughput of 15 requests/sec - upto 16 requests /sec. It is not even reaching 14 (well, except once)

How does it work? enter image description here

May be you might not be having enough threads in Thread groups to reach up to 15/16 RPS. Try increasing the thread count. According to the Throughput Shaping Timer plugins wiki page the formula RPS * <max response time> / 1000 can be used to get the number of threads that needed to reach the desired RPS, but it never worked for me.
