Spill Hole Research

Hey guys! So, since Gabby is gone and our material isn't in yet, I was doing research today about the spill hole and its size.  Every time we did a test run, the spill hole seemed to be too big.

We aren't sure whether or not to even use a spill hole...because we might just scrunch the top of it so that there is more air resistance (because it isn't so smooth.)

I was doing research (on the website below) and it said that the spill hole was about 20% the diameter of the actual canopy.  It is only about 4% of the area, so very very small.
