Forum:SH:3000 word GAs

Can I ask why the maximum word number for Good articles is at 3000 when the minimum requirement for an FA is 1000? I keep seeing articles that are GAs but have the requirements for FAs, like Tor Vizsla and Black Vulkars.  Commander Code-8  To say hi, press 42 03:50, December 1, 2012 (UTC)
