I took your first comment to imply the interpretation was mistaken and answered in a very general sense. I'm glad you were more persistent and that kwak figured it out. | |

| Oct 7, 2010 at 2:49 | comment | added | user603 | Hi Andy:> i didn't take you're comment as a critic. Your post is highlighting a key aspect of the question that neither Rob nor I (admittedly) understood. If anything, it illustrates the importance of collaboration. | |
| Oct 7, 2010 at 2:04 | comment | added | Andy W | @kwak - I was not criticizing your post, I agree with everything you said. I was simply wondering if there was some logic as to why someone would use the differences as instruments that I was unaware of. I can't imagine any situation in which the differences would meet any of the requirements for such a procedure. | |
