Maybe one f/stop underexposed, but still you have enough curve family information to make processing decisions.

Again the only thing you miss out on, is a few more steps of information that you could have had in the highlight densities on the right side of the graphs.

And the underexposure does not in any way impact the speed of your film that is revealed by the curve family.
