Well, you should always try to aim for an error of zero. Most of the triangulations I've done have been on a map with labeled cities. Then, the test just asks you to give the city where the epicenter is located. There really isn't a margin or error in these problems, just a right answer. So, try to be as accurate as possible and as long as your intersection point is at the right city you're fine. If you end up with a point halfway between two cities, you're in trouble. You have to either redo the problem or guess.winneratlife wrote:I guess that would work, but what is the margin of error allowed at most events?
Of course, different event supervisors could throw different types of questions at you and they will all choose their own margin of error depending on the scale of the map and how tough they want the question to be. It's possible that if they ask for an exact longitude and latitude the question could be a tie-breaker - that was the case on many Road Scholar tests I've taken.
