Making Super Diapers

This is my first time trying something like this and as you can see it was lopsided.

I am interested in ideas for a Super Diaper 2.0 test, and how to set up the diapers.

I am thinking this first test was 4 diapers, and one of them barely got wet although 3 were saturated / kaput by the end of the test.

I am thinking the next test would be 7 diapers possibly, an extra one in the center and two MORE on the leg area.

Ideas?
