Oh yeah, if they were entering data for tons of things each year and not just turning directly to the cherry blossom page that's a lot.

I live in Asheville and know tons of people who work at the NOAA offices here and that dataset alone is like 4 underground warehouses of weather data just from the past 200 years. Can't imagine something like that for 1200 years of records.

My job is also doing a lot of as built data entry for telecom networks though, so I'm used to hundreds of thousands of data points and that skewes my judgement.
