The validity of these estimates can be verified by counting the number of amino acids that remain unchanged under the action of the matrix M{\displaystyle M}. The total number ofunchanged amino acids for the time interval of the PAMn matrix is.
The PAMn matrix is constructed from the ratio of the probability of point accepted mutations replacing the j{\displaystyle j} th amino acid with the i{\displaystyle i} th amino acid, to the probability of these amino acids being aligned by chance. The entries of the PAMn matrix are given by the equation[11][12].
By using only alignments of proteins that had at least 85% similarity, it could be reasonably assumed that the mutations observed were direct, without any intermediate states. This means that scaling down these counts by a common factor would provide an accurate estimate of the mutation counts had the similarity been closer to 100%. It also means that the number of mutations per 100 amino acids,the n{\displaystyle n} in PAMn is equal to the number of mutated amino acids per 100 amino acids.
