True.
However, that still leaves nearly 100 puzzles, many of which have seen little or no activity. I've only moved up a few puzzles of mine that were open to Pros for 10 days or more with no questions or responses. I've also been actively working to move stalled puzzles up from the Rookie and Expert sections.
And while it appears as though the Masters have plenty of puzzles available to them (339 total), after subtracting the Black Hole puzzles (232), puzzles that are more than a year old, and puzzles featuring North Korean vehicles (for which it seems none of us have the resources to solve), there are currently only 31 active Master level puzzles.
