How low will a paracord net sag in a trampoline frame?

I am working on making a paracord net inside a 12 foot diameter trampoline frame.
I want to design it so that about 10 people at a time could fit on this, so say around 2,000 pounds.

Does anyone have an estimate of how far I should expect this to sag with all those people on it? How much does a paracord net stretch or sag? I am trying to determine how high off the ground it needs to be. It will have a static line perimeter, but I only want to use paracord for the net if possible. It won't be way up high like a normal tree net and I don't want people to be sitting 6 inches off the ground... Is a 3 foot height off the ground realistic?
Thank you!!
