I was just writing a guide on how to do a portion of my work at work and noticed that I did not know of a word that would describe the same outcome originating from a set of opposite causes.
The example I was working on was that if you had to check a large number of small items this will take time as while the boxes are easy to maneuver you will still have to go through a lot of them. Still if you have a small amount of large boxes this will take a lot of time as you have to spend time moving them around even if it takes less time to check them.
