I have been around here long enough to know that since I don't know what I am talking about, it's best for me to stay out of the discussion threads. It is killing me that there are people questioning the validity of models that they don't know anything about. "Well is the {insert model here} really able to {insert complaint about what it is saying here}?"
IF YOU DON'T KNOW WHAT THE MODEL IS SUPPOSE TO MEASURE, WOULD IT BE SO HARD TO SEARCH SOMEWHERE AND FIND OUT????!!!!!
