Development controls contrast. It would be difficult to tell what was proper development by looking at a photograph of a uniform surface. Ideally, you might set up a patchwork of cards which reflected light as Zones 1, 3, 5, 7, and 9 (or, more realistically, 2, 4, 6, and 8). Photograph them a couple of times, cut up the film, and develop as mentioned. That way you could get an idea of speed (from the low value) and contrast at the same time.
You used to be able to buy packages of reflection gray scale which were ideal for things like this. I don't know if they are still avaliable.
