For anyone else reading, we're talking about http://robert.mathmos.net/osm/postcodes/stats/ > What do the columns S0 and S5 signify? The s0 and s5 columns are the number of (geographic) postal sectors with 0 or <5% of postcode units having at least one instance on an OSM object. So if s0=1, then there's at least one postcode in every (geographic) sector. If s5=0, then at least 5% of postcode units exist in OSM for each (geographic) sector. (That's roughly explained in the abbr tag titles on the page, but not all browsers expose those to the user. I'll add some text under the table to clarify this, and also explain what "Geo Units" is.) The idea of having those columns is that getting those numbers down might be a motivating challenge for people. > What made you stop using the geopunk website? I originally only added it as a stop-gap as a quick way to display a map of the area covered by each sector. I've now got my own sector maps (albeit showing centroids rather than a boundary) but that fulfilled the original need. geopunk seemed overly commercialised by adverts for my personal taste and I didn't see it adding any value. Is there something that was there that you're missing? > Are we going to monitor progress with a taginfo script, like we did before? I'm currently recording the s0, s5, "OSM units" (i.e. unique postcodes) totals from http://robert.mathmos.net/osm/postcodes/stats/ along with the total number of OSM objects with postcodes and the errors as quoted at http://robert.mathmos.net/osm/postcodes/osm-errors.html every day. I intend to do some graphs of these when I get some time. I'm not currently storing any breakdown by postal area or district though.
