Metro Man, I know, it was just an example to illustrate the point that it's of no operational relevance whether the probability is 10 or 90%, it still requires the carriage of an alternate or holding. So why not just ditch the number or the term PROB entirely and just forecast it - the operational impact is precisely the same. PROB30 might give you a warm fluffy feeling that it's 70% not likely to happen but is operationally of no relevance.
