Roast guidance

We are getting a nice middle brown colour based on following settings: Temperature: 235C - Time: 15 minutes.
When cooling starts, coffee will continue roasting for a small while, cooling is slow in the beginnning. If cooling starts when the right colour is already achieved, you might end up with a darker roast than foreseen.
