Better late than never, I suppose:
The second column is simply the first column divided by the variance of
the response that have been OOB up to that point (20 trees), times 100.

The verbose option gives a display like:
rf.500 -
+ randomForest(new.x,trn.y,do.trace=20,ntree=100,nodesize=500,
+importance=T)
| Out-of-bag |
Tree | MSE %Var(y) |
20 | 0.9279 100.84 |
What is the meaning of %var(y)100%? I expected that to
correspond to a
model that was worse than random, but the predictions seem
much better than
that on the o-o-bag estimates from predict(rf.500).
