I'm trying to find a word to describe, given a stagnant (i.e. not improving) environment, the phenomenon of improving the local situation as much as possible, possibly even up to a fixed upper limit which is due to the environment.
Just for information, my use case: I measure the percentage of the actual improvement compared to the maximum improvement possible. Further improvement becomes more and more difficult as we get closer to the limit. So while a high value may seem better at first, it indicates a severe long term problem.
This question arose from working on an scientific article about P2P/Bittorrent networks, in particular the percentage of blocks available to all (non-seeding) peers in a network, often with availability < 100%.
