Before revision:  The extension is based on the approach of filling the missing elements to minimise the eigenvalue of the incomplete matrix . It means that the well-established values of the random index , a crucial component of the consistency ratio for which the famous threshold of 0.1 provides the condition for the acceptable level of inconsistency, cannot be directly adopted.
After revision:  The extension is based on the approach of filling the missing elements to minimise the eigenvalue of the incomplete matrix is minimised. Consequently, the well-established values of the random index , a crucial component of the consistency ratio for which the famous threshold of 0.1 provides the condition for the acceptable level of inconsistency, cannot be directly adopted.
