I have a thought that may make the game more playable to some people.
Allow multiple puzzles per post, but all scored at the lowest level.
That is, suppose I post 19 puzzles right after gremlin posts a new pattern.
I get only 38 points, 2 per puzzle. (Bonuses-penalties exacted later.)
Coupling this idea with a rule of (example) 1/2 hour minimum between puzzle posts by an entrant would get people to balance quantity versus quality.
