This is a false analogy in my opinion. SBR refers to subject lighting conditions and is not in any way dependent on either exposure or development. CI is a slope created by minimum and maximum densities that is measured after development and results from both exposure and development. It might be ok to say that one can develop to an anticipated CI, but to say that one can "develop film to a given CI" when the final result is not the CI to which one is developing is not reasonable. One can develop for a given SBR and may or may not get the desired CI, but the SBR has its own reality, i.e. it existed apart from and outside of the reality of the desired contrast. CI has no reality beyond its realization. If you develop to a CI and get some other slope than what was intended then what you have is another CI.
