It seems there is an error in the ECAT report. Could somebody confirm this?

Please, see the comments of Mats in the following article


Here a detailed explanation of the problem. If somebody with the knowledge can explain.

They are discussing about an inverted clamp that can cause the COP 3.
Please i need to know if this is destroying the report. 🙁
