The statement about the ellipse is correct, but I don't believe that it applies to fluid dynamics, especially not in this particular case (but then what do I know?
).
As has been doscovered by many people now, The cascade is easy to imitate, but very difficult to reproduce: there's a fine balance between jets and cups that must be tested, to find an optimal configuration (again, if you have money/venture capital, *call me* !!!
).
Cathar has been trying to get more jets, but is hitting close to fabrication limits, if he hasn't hit them: 100 jet may be possible, but it's not going to be easy.
Good luck, and keep us posted!
