They aren't, every official table has but a handful of numbers filled in, only Lyra2Rev2 and X16r have a decent amount of info on them but nothing is concrete, that is the entire point.
One thing they are consistent about is suggesting that in most cases the best configuration is one acorn per gpu. Interpretations can vary but you seem awfully keen in thinking yours is the only one
Last time I checked SQRL mentions standalone mining in some capacity using the CLE-215(+) acorns, why are you trying to decide what their products are intended for? Now that I think about it, did anywhere I mention I'm interested in solo fpga mining? No? Thought so. I merely said proper information on a shipping product is lacking in every aspect.
Thats because those are the 2 algo's you get the most bang for your bucks on, so they have prioritized them
In case you want 1:1 you buy a nest x4 2 m.2 to pcie x4 converters, and some pcie x4 risers, and you can have 2 gpu and 2 acorn on the nest x4, and again due to the dma engine all high bw traffic from gpu to acorns and back should he handled on the nest x4, its not that hard to imagine what kind of setups you can do, but i would most likely have bought 10 times more acorns if they could confirm that this is the case.
Im not trying to decide anything just stating facts, if you go dig arround here you will also see it mentioned that standalone mining is not that profitable on them, You can see by looking for example at the tables, that for now primary focus is on lyrarev2 and x16r.
Because thats where you get the most boost and therefor profit with this kind of setup.
