[RTTY] WAE rules for off time?

[WW3S]

Anybody know exactly what this means:

4 Off Times:

Single Operator stations may only operate 36 out of the 48 hour contest
period.

"The total of 12 hours off time may be taken in one part but not more than
three parts. The off times must be shown on the summary sheet. If operation
is interrupted for more than 12 hours the three longest off time periods
must be a minimum of 12 hours."


If operation is interrupted more than 12 hrs, then I'm not going to have
more than 36 hours, right? If I stop early Saturday night ( say 6 oclock),
and don't start again until 7:00 am Sunday  (13 hours off time) is that ok?

Also, is there a band change restriction on single-ops? I see that multi-ops
can only change band once every 10 minutes but don't see anything for single
ops?
