How to get the maximum QPS in wrk2

[Triple-Z]

Since the wrk2 using the --rate / -R to represent the constant throughput load (which is called RPS), I can't get a maximum RPS value by unsetting the --rate parameter, so how to get a maximum RPS via wrk2 just like the wrk do?

I would like to know the answer as well

A solution I use is to perform some sort of search algorithm (eg. binary/golden-section) with range of -R values till there’s no more increase in achieved-RPS to find max
