I like that you all are researching the Relative Nina.  It must be something like looking for a moving target inside another moving target.  A La Nina "Event" being different than a qualified, so to speak, "Historically Recorded Event".  Do you look back and adjust your measurement requirements versus the correlated coupling of atmosphere during non-qualified events?  As looking back is always difficult for reducing biases, have you developed any real world predictive tests other than computer models?  That sounds like a near impossibility to me but I never know.
