The only way \_I\_ can tell if Powers is wrong and you are correct is to  
compare the predictions of your model and his. I am familiar with his model.  
What does your model predict? How have you tested its predictions? How much  
of the variance does your model explain. (Powers' model explains roughly  
99%, but it needs to be tested on your data.)
