Peter, Would you not need two groups that were re-arranged? One into the perfect Housel (since we can presume few of your control hives start that way; unless you re-arranged them, the odds are greatly against it) and the second group into some other configuration that is not the perfect housel, but is re-arranged. Otherwise, your study may only gauge the difference between those rearranged and those not, rather than Housel versus non-Housel. Karen
