Can calculating average request/s start after delay which is set in population parameters?

I set the population parameter "delay" on 1000 s. This is needed in order to allow application to be up and running before starting performance test (on jenkins). But, average request/s is calculated from the start of the test and calculates that delay time too. So, for my application it means that instead of ~ 450 request/s my results show ~9 request/s.
