Mixmode

Mixmode controls the algorithm for mixing the squares:

auto automatically switches between "random" and "correct" modes depending on the quota of dancers that have to sit out compared to the number of dancers that can dance.
random is usually a better choice if few dancers sit out.
For choosing which dancers will be in the next tip, this mode will only take into account the quota of tips a dancer has danced compared to the tips he has sit out. Dancers with the worst quota will definitely be in. If dancers have the same quota, a random choice will be made.
While "random" is a good choice if only few dancers sit out, it might create a feeling of unfairness if many dancers sit out (although the quota of dances compared to sit outs will definitely be correct).
correct is usually a better choice if many dancers sit out.
In addition to the "random" algorithm, also the duration that a dancer has sit out will be taken into account. Please note that this might lead to having always very similar squares under certain conditions.

Note: In any case, a dancer that has sit out one tip, will dance the next tip (except he volunteers to sit out of course).
