why virtual waves help

The point of such a challenge would be to focus on the classification algorithms with a standardized dataset that different people can try to get the best results they can with it. Compared to the conventional challenges that currently exist the results would be much more repeatable and smaller differences could be more clearly discerned.

Also, IIRC WaveSim does store enough information to derive most if not all possible attributes (including PPMEA based ones), due to the way that I added PIF support to WaveSim.
