That's the range of the 21-step Stouffer wedge I have. The 21 steps of 1/3-stop each covers a 7 stop range, which compresses to about 5 stops on the film due to the gamma of 0.6. I set the exposure to clip the beginning of the toe (left side of my curve doesn't start flat), but that's still not enough range to see where the film starts shouldering-off. Oh well, that's the best I can do.
