As someone looking at algorithms for managing buffer bloat, this resonates.
In IP routers, the goal is to keep the congested link busy. i.e., Idle time from a momentary hiccup is wasted time. You need a small buffer to do this, but piling on more data adds latency without actually doing any good.
Algorithms like CoDel realized that a lot of previous attempts to make this were noisy as heck. Minimum latency through the queue is the signal that makes sense. Everything else is misleading or gives inaccurate predictions. Why should it be any different for managing tasks for human workers?
