It is superfluous because (were it not for the coding bug) I did switch to the low # side.
Unless all three country numbers are close, there is always a low number side. That low number side will be that way for the hour (usually many hours) that it would take to change sides per the current code. The numbers don't swing drastically in less than an hour. As I said, superfluous.
My point was that under my proposed rules you would have been able to make the switch.
