I have another related question.
"If you're not overcasting the same GE, which GE out of the 5 is picked at random."

so if say all the spots were filled, and one of them was well of misery with 100 gems into it, and another was sea of ice with 35 into it, and Alpine tried to cast earth blood well with 80 gems, he is equally likely to end up rolling against WoM as SoI?
