ENSO is not best modeled as an "Ensemble". It's a standing-wave mode with a fixed spatial configuration, which means it's a single collective fluid behavior, not a statistical ensemble of outcomes. At least that's the premise I use. If you want to do it your way and treat it as "Crosstalk Noise", go ahead, but it won't help me any. I took classes at the graduate level on noise from this guy, so I do know the topic well
