I also met some nz government workers teaching ppl how to farm. They said most Mongolians weren’t interested in working with the dirt. Understandable given their long long history as nomads.
I’ve spent a decent amount of time figuring out to make porcelain tile. The most reliable way to do so and avoid cracking is to use a plaster mold and push slabs of clay into it. Cookie cutter and other slab methods produce too much cracking without heavy duty equipment or maybe a different clay formulation (I’m using standard porcelain which isn’t the easiest material)
As others have pointed out for the authors discussion this fact doesn’t really matter.
However what does matter is that the authors probably is not estimating the average correctly partially due to this bug. If they scaled without fixing their excessive string storage, they would probably find their estimate to be off.
Even with the fix I’d be surprised if the underlying distribution of data per user is normally distributed.
