This section of the site allows you to browse rosters based on various mimimum ratings. In the past, each page contained a list of pilots who had completed that rating, even if they had also completed subsequent ratings. This resulted in the V-1 page having every single pilot. The V-2 page had everyone that completed the V-2, V-3, I-1, etc.
The pages were changed in late 2008 to show pilots who have completed up to that rating, but not beyond. This allows members to get a feel for how many other pilots are in the same boat as they are.
