SPM and launches per minute are just different ways of saying the same thing unless you are launching so many rockets that space science is no longer the bottleneck for research. I haven't gone super far into the endgame, but in my experience this is pretty uncommon. also personally, I find rocket launches to be too abstract to care about as a goal. I get where you're coming from with the infinite science, but I find it a lot more satisfying when every new tier tangibly improves the efficiency of my factory.
