This is one thing that has puzzled me about people taking a year or so between kyu grades. Is there a reason why some organisations/clubs/dojos test more sporadically than others?
This is a perennial discussion item in the testing forum. The answer to your question, obviously, is "yes" -- otherwise they wouldn't do it. In USAF, "a year or so" would actually be testing at a pretty brisk pace after the first couple, and 2nd kyu to 1st kyu is 300 practice days and two seminars per year.
