I researched a more on this topic, and as I understand, the threshold needs
to be set adaptively. Here's a paper on the topic:
http://homepages.cae.wisc.edu/~ece533/project/f03/yangyang.pdf

Let me know if I'm in the right direction. Also, does the proposal need to
have all the specific implementation details at this point? Because that
would take a quite a while, and it's also very hard to know beforehand, in
my case.
