shows me that the execution time deviation of the jobs of the first task in the chain (PID=1926) is getting larger. Does this deviation has to do with the time it takes for the jobs to write to the pipe?

What's more, when I enlarge the chain, the execution time deviation of the jobs with PID=3678 varies drastically.
