What about other recipes which remain close to the average in my data ? Pet food for dust relics is more likely to be in high-frequency pool, due to symmetry reasons with other Pet foods costing relics. Similarly, 2 Runeshards recipe is more likely to be in the lower pool. For 3KP, as 1KP is the only other recipe in higer pool, we can't guess without data. Is it more far to the average in your data ?
Finally, there's the case of supply windfall 15%. It used to be lower than average until I've got a ton of these recently. So what does your data say ?
Note : I think CR33% and SW100% are in the higher pool since other CRs and >25% SWs are high-frequency too.
