Defining K Value

[jpk15102]

I believe it is a more accurate process of defining K when you use a temperature value that is the average of the body temperature over the interval you have approximated dT/dt within. In order words I would recommend modifying your define K code to average the temperatures of 85 and 74 degrees rather than simply using the final temperature of 74 degrees. In doing so, it is a better approximation of Newton's Law of Cooling. Also I believe using the K value from this method creates an analytical model that more closely fits the two data points of 85 degrees at 11 and 74 degrees at 1.
