I think there are LOTS of inconsistencies in the rules, SOPs, OMs etc. I think in those situations one should use common sense and since there's some freedom of interpretation - just choose the option that makes you feel better

As long as one knows the regs and is able to back his decision with them - no one should question it. Knowing the rules and those inconsistencies might in fact be an advantage. Want to go? The rules say that if the destination is below minima, you just need 2 alternates. Don't want to go? The rules say you need the wx to be above minima to proceed - it's your choice
