Something to kick around. Is it possible that you can put up a site where people can post their own results?
Possibly something as simple as Bach Strad 37 ML (Y) or (N)
I asked rowuk but by his own admission is as busy as a one legged man in a two legged race.
If you can do this, it would make the process easier for the general population to see the results and give people even a greater ability to participate.
As for the BIAS,
Now that's a great idea!! The BIAS could be used to compare human results to the machine results. I know very little about the device other than it cost + 5000 euro. However, what a great idea for someone to do their doctoral dissertation on.
