1. I think the cyclomatic complexity does not tell anything about how good and useful an entry is.

2. The code metrics are still often displayed wrong. Check out this example:

Here is seems that four of the five metrics are very low:

However, in three of those four categories, the submisson gets the best values possible (0.0 M-Lint messages, 0.0 filename clashes and 0.0 cloned code):

Maybe one could check the computation of the green bar visualization.
