I was just in a game where I had 11 supply centers, and had solidified the draw by locking the leader at 17 supply centers. There were 5 players left at the time. Two players had 1 supply center, one had 4, I had 11 and the leader had 17. I didn't actually mean to lose when it happened (forgot to support Venice), but I did decide to start moving against the ones left. A draw with 3 would have been better than 5. Either way, I got more points by not drawing, since I ended with 13 supply center and 12 or more is better than a 3 way draw.
