Inevitably, the wbridge5 robot places very high in the rankings, perhaps because it understands the opponents' and partner's signals perfectly. In the Nov. 17 tournament, however, I managed to beat the wbridge5 robot. In fact, it looks like I beat out all but one of the humans.
What this probably means is that I took a few against-the-odds positions and they paid off. Still, I'm happy to have beaten the robot. That probably won't happen again.
p.s. Lest you get the wrong idea: 67% is way outside my usual range -- I currently average around 55%.
