There cannot be a definitive number, but one thing I am sure of....after you have a large sampling of matches, the median will be a better number than the average. Throwing out the very best and the very worst matches should leave you with a much better representation of how you play, provided, of course, you have a large sampling to begin with. As for 1 point matches, I would think that if you took a median sampling after 25 matches, and then again at 50, and you saw almost no change, you could probably feel fairly confident with the number and pretty sure it won't change much if you did another 50.

Obviously, I am against averages since one or two unusually good or unusually poor matches can affect the numbers far more than I believe they should. What we really want to know is where you are likely to play on any given day, and I believe the median is far more reflective of that than an average.
