-This works by starting at a 1 second `base_interval`. Setting the `multiplier` to 1.0 means each subsequent try will increase 1x, which is still `1.0` seconds, and then a `rand_factor` of 0.0 means that there's no randomization of that interval. (By default, it would randomize 0.5 seconds, which would mean normally the intervals would randomize between 0.75 and 1.25 seconds, but in this case `rand_factor` is basically being disabled.)

 Same thing can be done by passing `backoff: false` option.
