@Lt72884 Given the quote below, could you post up your OR sim that says that the optimum delay for the LOC IV is 14 seconds? A picture of the fins would also be nice since shaping on the fins has a big impact on the altitude/optimum delay.
As to the OR Sims. The LOC IV with an H550 gives optional delay as 10.1 sec. The Default delay for this motor is 14second so possible this is where the student got this delay time from. With a 14sec delay OR says the rocket will be descending at 70f/s when the Main chute deploys. I am not surprised it zippered but the other flights got very lucky.
