I've decided to run 4 flights this time around. The first one is a simplified roast progression. 2 roasts that end between cracks, 1 that ends right at the start of 2nd crack, and 2 that go beyond the start of 2nd crack. I do something like this with every new coffee I bring in, except I'm usually tasting more like 12 roast levels.
The 2nd flight deals with overall roasting time in a light roast with a baseline roast, one with all the difference front loaded to before significant roasting chemistry is happening and another where the difference is distributed proportionally through the roast.
