I see you used the rules for 2006/2007 as max rules for Brazil. I'm not sure
this is a good idea. And as far as I can remember it isn't what we have been
doing in previous years.
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.
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.
My 2 cents,
Rodrigo Severo
