Would be interested to hear how the old school boys would describe blocks like the Storm as being anything other than "constrained submerged jet impingement".
The Cascade isn't really submerged JI though, and I've even said as much multiple times in the last 18 months. Originally designed it, modelling it with traditional JI theory, which strangely enough seemed to work well enough for estimation purposes, even though I've long since come to an understanding that it's not really JI, and rather it was merely a way to exact/maximise high turbulence mashing within a constrained area, much like its derivative inspiration being that of a faucet at full blast in a tall glass.
