the whole square pocket/hole idea is based on something Cathar said...

They really are symbiotically linked. Quite a few things at play on that one.
You want the structural strength, true, and the cup walls give you that, so they are a necessary evil. The cups walls are also there to contain the off-flow from the jets to stop the jets from interfering with each other, so again they are necessary.

now what I am thinking here is that by having many round holes in a pattern, the wall thickness between the holes are far from being a constant...that is it changes depending on what angle you are looking at. By having a pattern of squares, it is much easier to minimize the wall thickness of the cups....to more of a constant.
Disadvantage is is that it makes it more complex to make, but not overly so....especially for a non-production block.
