Calculate Time Step for Pathfinder Library

How do you calculate the time step for the Pathfinder library. I think it is the time for the control loop iteration, and if so how can I calculate that?

Thanks,

I believe it’s 20ms if you’re using timed robot

Thanks for the reply,

We are using Iterative.
