I can's show it here but an actual survey shows variance between Labs of
-37 to +25% in the 125Hz band. Same test, same materials. Real Labs, USA, proper survey.
Your talking about the round robin which is not what we are talking about in the same lab. Yes there was a test and guess what they found a difference from one lab to the next lab. The good news is Riverbank, who we and most larger acoustic companies use fell right in the middle. Meaning it was not to high or not to low. In fact you can use them as a base line which makes them 0%. heh
