<br><br>As far as I can recall we have been using "only" rules for election years (as 2006, in fact the even years) and wishfull rules like "Feb Sun>=15 0:00 0 -" and "max - Oct Sun>=15 0:00 1:00 S" for others (the odd non-election years) in hope the pattern will stick.
<br><br>None of us can predict the future, I know. I am only taking the time to write all this as the "wishfull" rules above have worked before for odd years. I bet they will work next year (it's just a bet based on previous years). Maybe it would be better to use "max" rules as the ones we have used before.
