Is there a reason you all are using so many gores on these smaller parachutes? About 8 years ago I compared the descent rates of 96" parachutes (semi-ellipsoidal) that had 8 gores, 12 gores and 16 gores. They all used 16 shroud lines. I could tell no difference in the descent rate calculated using the same drop weight. The important factor was using the same number of shroud lines to form the canopy better. It also resulted in a lot less sewing.

I'll be starting a parafoil here soon to color match this parachute. I'm still trying to find some math for parafoil size to drag ratios. I might end up using comparable area to a flat parachute to start. Of course the shroud lines on a parafoil get more interesting.
I also made a 4 gore 12" 50%ish hemispherical parachute for a little action figure to come down on as well
