227,482 amicable pairs have been found so far, ~340,000 are yet to be found according to my estimations. Due to the way this search is organized and how amicable numbers are distributed, I expect almost all of those ~340k pairs to be found before the search reaches 50% in a couple of weeks, and only a few thousand of new pairs will be found after 50%. So if your target is to get some of the discoverer badges, now is the time to crunch with everything you've got.
Since there will be only a few new pairs after 50%, this is when I'll introduce credit badges.
