The updates to the database aren't records of real-time, real-world
events; They're just mappers updating parts of the map. Anything which
analyses that, rather than the data itself as a whole is just
navel-gazing. It tells you something about the project, but not the
world it's mapping.
You're not missing out on anything by having minute-old data. We're not
recording how the world is changing, we're just making our map more
As for wanting updates in a different format: Patches Welcome.
