Quite right, now. It used to work. It was a feature introduced by [Bug 
192] Unfortunately, a change made 18 months ago that is marked "Allow 
ntpq &1 associd use without preceding association-fetching. Use libntp's 
months[]" removed the code that clamped the index value at the maximum 
association id. I just filed [Bug 2220] to get it put back.
