Don, Thank you for posting your question on the forum. I have spent some time looking at your code to see if something in LabVIEW or from your coding jumped out at me as causing the problem. Everything looks very clean, and, having not looked at my statistics or correlation functions in a while, I did not see anything obviously wrong.
One thing I did notice is that if you select a different subset, such as 0 to 100, then the normalized correlation does come in at less than 1. Because of this, it leads me to believe that there may just be something slightly wrong with the code and the steps you are doing. Again, from a programming standpoint it looks just fine, and maybe someone else out here who deals with statistics and correlation more often may be able to shed some light on the math side of your application.
