The problem I see with this is that people have such widely different ways of meteting and determiing personal effective film speed values that the information I derive from sensitometry would not be particulary useful in a practical context.

Film contrast is another issue because if you develop the same way I do using the same film you should get the same results. That is why I am more confortable posting results for film CI than for EI.
