So I plan on getting a binder design excel for my level 1 certification. I'm looking for RockSim data for OpenRocket to test some motors and I found 2 files but they are about 400 grams off from eachother and I'm not sure which one I should use. Also I went ahead and tested a H123W motor in one if them and the thrust to weight ended up being 9:1, is that ok?
