Optimize for time spread of particles hitting an accumulator

I am using the charged particle tracing module and an accumulator to count how many particles hit a certain area during the simulation. Then I use the comp1.cpt.wall4.bacc1.rpb_sum expression as my objective function to optimize for the most particle hits, and this works well.
I can also post-process the data to see the accumulator value at all time steps, and calculate the time spread (time difference between when the first and last particle hits) as well as the full-width half-max time.
Now I also want to optimize the model for minimum time spread. How can I calculate/express this as an objective function?
I read the section in the Particle Tracing Module user guide about auxilary variables and residence time (Ch 2). I think it's close to what I want but I don't know how to use it to calculate something like time spread for the specific accumulator.
Thank you!
