IWR6843AOP: Zoom FFT effect on processing time

Hello,

In the high accuracy lab from the industrial toolbox, one section mentions a tradeoff in latency and resolution between different devices. Is there a resource you can point me to to help understand how different datapath configurations and chirp profiles effect latency? What would the expected latency be if we were to use a zoom FFT similar to that lab? How does that compare to the typical? If I implemented something similar on a different part (specifically, AWR1843AOP), would that behave very differently?

Thanks
