Since 2000

Ivey has won 5 different years (6 if you include Asia)
DN has won 3 years (4 if you include Asia/Europe)

They have won 8/14 years excluding Europe/Asia.

Since 2008 though, they are 2/6 excluding Europe/Asia. Bigger fields/better players/Ivey skipping out.

I thought it was slam dunk but maybe just +EV but not much.
