I still can't believe how the SPARQL data cannot reliably reproduce the same data in an existing table. I once tried to extract the population and surface area of each country using the official QL, just for reproducibility purposes, and gave up in frustration as it gave me sea area and combined area instead. I instead copied, pasted, and merged two tables, and stuck it in a file somewhere.
