I've decided to take the what I'm calling the "DonGuy47 Challenge" for September and play every board the game gives me... even if I see if the top score is 275 by one of our top five players (the guys/gals who routinely set the record for boards in the range of of 675-775). I will freely admit that I'm a 'board skipper'. There could be an element of me wanting to raise my per game average, but I'd say it's predominately because I enjoy myself and the time more if I'm trying to squeeze 400 to 450 to 500 points from a 'good' board in two minutes.
Anyway, my per game average is certain to go down this month, perhaps by a crazy number. However, if I play a lot of boards where I can only get 200, 225, 250, and if I study what was available afterwards, I think that that approach could help me even on the better boards where the key limitation is time, especially if I learn to spot/use some high point words that aren't a current part of my repertoire.
One other thought as I was thinking about goals after seeing your responses - I realized that I do have another longstanding goal. Namely, I'd like to have the record for a board that has been played 50+ other times. I think I may have accomplished that once last spring, but I didn't take a screen cap to verify that later.
Edit - speak of the devil! Second game of my September DonGuy 47 Challenge!
