So I’ve been toying with the idea of just going with groups of four and then I would have all the groups in both sections being the same size. So is that better or is it better to do an experiment where I’ve got one set in groups of three and one set with groups of four? Then, would they somehow be unhappy if, you know, if you were in one section and you were in a group of three but you could have been in the other section and been in a group of four?
