I don't quite understand the question, but I will try my best to answer it. I went back and watch a few videos of the fountain. From what I can see and know for a fact...most of the jets are on the top of the tiers. There is a pool on the top tier that cascades over the sides and down the 3 tiers. There are other jets positioned along the inside of the bottom tier that shoot into the center, but other than that I am pretty sure there are no other jets ON the tier steps! (unless they have added them since I last saw it in person)
That fountain always amazed me, and most guests overlook this and don't take the time to actually watch it perform. I remember when I was working the TIP BOARD at Epcot I would get a little bored and 'direct' the water show(even though they had someone do this at times during the day) I enjoyed it, it was fun and kids just thought I had magic in my fingers when I would make the water jump with a wave of my hand! LOL! God, I miss those good ol days!
