    Well, your example is perhaps the worst one since you wouldn't be
    decreasing the quality of your stats very much by only doing the
    sample in the men's room ;). I guess you meant the woman's room.

    No matter how you see it, the larger the better (in the worst case it
    won't make a difference). Certainly if I could work on the quality,
    that would be more important than adding 1 more user. But I can't work
    on the quality.
