TopShelf2010: many of the top players have already made the adjustment to PCEA with the current dot speed. It doesn't make sense to keep making changes. Let the players make changes to their own game.
Don, I respectfully disagree. As you yourself have mentioned in many threads, the PCEA is still subject to change. Players who have already made the adjustment could simply select Slow for the dot speed. Others who have not could select Fast.
More choice is always better than less.
