the ETA model is basically the predecessor to the NAM - and, I think it was DT who said if you had agreement between the ETA and the Euro, it was basically a lock (this has not surprisingly been proven NOT to be the case always, but still).
yeah - I mean that makes sense. Bottom line - as they are arguing - is to be consistent. Maybe they need some way to categorize and classify prior calls that can be quickly referenced during these reviews - so they can be consistent, or at the least if they decide to change how they are going to call it, they can reference past calls.
