Hi Richard,
Thanks for following up on your study and responding to suggestions. 
Please post your slides to docDB. I believe you already have an earlier 
version posted. The google docs is convenient for short term, but most 
of us would be hard pressed to find this study at a later date.

Thanks, Elton.
