 ; DTMF Reverse Twist and Normal Twist is the difference in power between the row and column energies.
 ;
-; Normal Twist is where the Column energy is greater than the Row energy
-; Reverse Twist is where the Row energy is greater.
+; Normal Twist is where the row energy is greater than the column energy.
+; Reverse Twist is where the column energy is greater.
