The reason I was persistent is that the difference between Grade 0.5 and 1 is about the same as between Grade 2.5 and 3. So even if you get a negative with less contrast in it, the dynamic of the contrast filters is roughly going to be the same, regardless of where on the contrast scale you end up, if that makes sense.
But, it's a good thing to see what happens when we develop the negative to different contrast indices, so see what effect it has on the print. How the negative affects the print is, to me, one of the most wonderful things to understand, and learning how to control it is the best thing that has ever happened to my darkroom printing. It makes everything so much easier and predictable.
Have fun, and good luck!
