The trick to the Cascade was to guage the cup diameter to present the cup wall just after the point of "rebound" from the cup base.

So the diameter of the cavities are based on the geometry of the jet which in turn is based on the velocity of fluid and ratio of jet height to jet nozzle diameter
You have designed the cascade so that it does something like in the modified diagram below.,..?
