Ahhh - well that makes a lot of sense, but I still think the percentage
on the slider should reflect the commit-percentage that would move the
user to the "others" group. This could be done in different ways.
The easiest way would be to just set the slider to have max at 50% and
then use 0.5% steps.
Another way could be to set the max of the slider to whatever percentage
the second most active author is at. - But I guess this could be a
difficult calculation to make - esspecially calculating the step size -
and in some cases make for a wierd slider.

Anyway - these are just my thougths and certainly not something that
will haunt me in the future.

Keep up the good work Stefan.
