I'll use 98mms as an example. Big gaps(outfall) at burr touch/0 let big chunks though. Hard to build pressure when your particle spread is skewed towards the big chunks. SSP Low Uniformity doesn't do "classic" 9bar espresso because of that big outfall. People like them for fast low pressure turbo shots though. The smaller aperture on the High Uniformity skews that the other way. Higher fines higher body traditional espresso. That other anon is saying the zp6 is less versatile because at the zero point, there's still a ~250micron gap. The k-ultra on the other hand does high clarity filter, but also can produce enough fines for espresso.

>seems ridiculous, frankly
zp6 was designed with a large "outfall" for filter. No matter how fine you grind, there will always be big gaps for large particles to fall through. Tightening up those gaps would let the beans go through more breaks, creating a higher proportion of fines to create pressure in espresso. Yeah you can rip short extraction time turbos with zp6, but you're not going to be able to hold 9bar for 30seconds without a high resistance/pressurized basket. Wrong particle spread for that. Heres a side view of 98LU and HU to so you can see what an "outfall" is.
