Hello. I am using an ejection Calculator to calculate charges for my 5.38” diameter rocket. The calculator program recommends not having a pressure of greater than 300 psi for this size of tube. I have ground tested with 2.12 grams and feel like maybe even a little more powder yet would be good. The calculator is however recommending I use no more than 1.9 grams so I am already over their recommendation without increasing it. Is it ok to use over the recommended amount as long as ground testing from a distance? Better to blow it up than not blow it out, right
