Actually, I wouldn't be surprised if more than one of the above was true. He offers lots of conjecture, no data to back it up, and proceeds to make sweeping generalizations about blocks he has never seen nor tested.
Maybe I'm wrong - maybe he has some numbers to back up his currently empty words... if so: Lets see it!

No, i don't want to decrease my level to the same as you. Why are you criticising personal things on me, that doesn't concern you and that have nothing to do with this. Not enough good arguments have you?
There was a time, where i really liked this forum, because of its intelligent and nice users. But since i write more and more here, the users become more and more stupid, are flaming all the time and have no respect of another person in any way. Thats truly sad.
What Balefire wrote here is an example of how unqualified and stupid a conceited User can write post when he left its mind anywhere else. I would be hardly disappointed if there are no more real arguments than just this offense.
Why don't you expect another company behind every small criticising argument?
Are you so frightened that the capitalism is eating you?
Learn to live with criticism, make something of it!
He wanted numbers:
I cannot give any specific numbers of the friction, because of different scenarios, pumps, tubings etc, i can just prove that it is definitely there and that there is definitely a point where it stops to be effective. And i can give you some hint how you can calculate it for yourself with your ammounts.
The goal of the Cascade XXS was, to have the best overall water distribution. This goal was reached with much more jetpipes than before. Bit has the performance also grown with the better water distribution?
I think it don't has to.
When there is Turbulence in the game(what i expect), the friction squares proportinal to the velocity, that is what everybody should know who builds watercoolers. So if you double the cross section of the jet, the velocity inside the jet will go down nearly the half, but friction will go down even more. So, with many small tubes and a cross section of 40mm² you will have a worse flow than with less tubes and a cross section of 40mm². Everything clear?
Thats why i think the cascade XXS was a failure and thats why i don't even believe it was better than the original cascade. And that can also be the reason why the storm performs better than the cascade with less jets.
Fluidus, one Member of my Forum in germany, made some tests on this, some time before Cathars Cascade, even before the whitewater.
he measured, that the ideal jetdiameter for a very short jets (with less friction) is something around 1.2mm with 1/2" tubing and an eheim 1250 and the ideal jetcount is 9x. For long jettubes its even more, because of the inner tube friction.
he didn't included cups ore other structure on the baseplate, so with the jetcount, the bpsurface increases also, but i think you can view his very good work also on your own:
