Yes, stochastic/FM is quite different. We HAD to use Curve 4 and a 25 point correction to get the gray balance correct. Otherwise, the actual curves will depend greatly on your ink, the BATCH of that ink, the blankets, and chemistry. ALL of that becomes more critical with getting stochastic corrected. Once done, it is awesome! You also need to test a range of dot sizes. We tested Kodak, Fuji, Agfa, and Heidelberg plates, at 2 different dot sizes along with two chemistries and two different ink manufacturers to get down to what works best for us. Because the dots are SO small it is very sensitive to getting it all right. The results and stability on press once all that is established are really impressive. Just brace yourself for some serious work, test/check frequently, and put controls in place for every step along the way to keep it dialed in once you get there.
