please fix circadian or give us an option

[Tad Carlucci]

Any change would probably cause far more disruption than it would solve any problems. If a change were to be made, though, and looking at the comments and rationales, I would suggest that none of the cycle lengths suggested would have the desired effect. To achieve that, I would suggest the cycles lengths should meet the following criteria:

Hours awake longer than Hours asleep
Hours awake and Hours asleep both prime numbers greater than two
Sum of Hours awake and Hours asleep should be relatively prime to 6, 8, 12, and 24
The smallest values which satisfy these are 7 hours awake and 3 hours asleep. The next pair would be 11 hours and 5 hours.

But, the decision is best made prior to launching a breedable product. Once launched, any change should be strongly avoided due to the disturbance it would cause.
