Once you have developed a profile for a coffee you want to precisely duplicate that one in future roasts. Artisan allows to load this successful profile in the background serving as a template for your production roasts. While seeing the delta of your current roast curve and that template helps you to decide if you should slow down or speed up your roast at any moment, especially if zoomed into the graph somewhat. However, often a numeric value expressing this delta is easier to work with. What about adding another LCD to show this delta?
