Degree of roast is the never ending project. I wanted to take new 
pictures for the chart, now that I have better gear, and some ideas 
to correlate single bean macro images, groups of beans, and ground 
coffee with the SCAA discs. I have an agtron too, an older unit, and 
actually have never fired it up! (Found it used...) But that would be 
great for reference. It's "Project 8342.6" on my list. But an 
important one nonetheless.
