title: Jmeter - concurrency thread group with throughput sample
body: <p>I have a JMeter test plan with a concurrency thread group and a throughput shaping timer.
  below is a screenshot of the test plan.

  The post requests are two requests which are sent one after another for a device. there should be 200 transactions/requests needs to sent per sec which I am controlling by target concurrency in concurrency thread group,  start RPS and end RPS in the throughput shaping timer.
  the total TPS should be 200 ( sum of the first and second requests in the test plan) and the device would be different in each thread. can this be achieved with the above test plan. I see that post-event 2( second post-event in the test plan) are not sent for some of the devices towards the end of the test.</p>
