First of all, welcome to the forum, Joey! And good luck on your L1 flight!
As Buckeye mentioned, your delay is at max delay time of 14 seconds.
Aerotech now supplies motors with a full-length delay and the user adjusts the delay element for the flight as needed. In the sim, you manually change that when selecting the motor.
You can do it with one iteration. Select the motor as OpenRocket loads it, as you have done. Run the sim and look at what is calculated to be the optimum delay, as Neil has pointed out. Select the motor again, and this time manually change the delay to the Optimum delay of 9.5

You may have already figured all this out, so this is posted for the benefit of others who may read it.
As Mark already said, motor delay is not very precise. Acceptable tolerance for motor delay time, by NFPA Standard:
"The ejection delay must not vary more than 1.5 second or 20% (whichever is greater, up to 3s) from average."
In this case, for a 9.5 s delay, any ejection time from 7.6-11.4s is in tolerance. Build your recovery system accordingly.
Consider the optimum time as a whole number at best, and then keep in mind that you'll set it by twisting a drill bit into rubber with your fingers.
This is all the information I need.
This forum is full of very sharp and helpful members who are happy to share what they've learned. In no time, you'll be doing the same!
