<br><br>As far as I can recall we have been using &quot;only&quot; rules for election years (as 2006, in fact the even years) and wishfull rules like &quot;Feb&nbsp;&nbsp;&nbsp;&nbsp; Sun&gt;=15&nbsp;&nbsp;0:00&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -&quot; and &quot;max&nbsp;&nbsp;&nbsp;&nbsp; -&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Oct&nbsp;&nbsp;&nbsp;&nbsp; Sun&gt;=15&nbsp;&nbsp;0:00&nbsp;&nbsp; 1:00&nbsp;&nbsp;&nbsp;&nbsp;S&quot; 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 &quot;wishfull&quot; 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 &quot;max&quot; rules as the ones we have used before.
