Tom,
Your chicken looks great!
As for the question on the programming, if you are going off of a program for food temp, then that is what you are able to program in each program, that or time and temp of the box. If I understand your question correctly?
But I have three programs set up for mine, P1 is a ramp up temp, P2 is a smoke temp and then P3 is a hold temp - all of these are set for a specific amount of time. If i were to change the cook to a food temp, I’d change out the second program to cook to an internal temp and then go to the holding program.
Hopefully that makes sense.
