"*If data you removed is still there then you have operationally done something wrong*."
Thanks Andrew for mentioning this, that's likely what has happened - I screwed something up and only thought I had removed the bogus data. In answer to your other questions, I tried to follow verbatim what Tom has outlined in his article, but most likely I didn't. I just now browsed /var/lib/weewx/weewx.sdb and the data I thought that I had deleted is still there <sigh>. I'll have another go at it in a moment, but am also wondering: is it practicable to delete the entirety of /var/lib/weewx/weewx.sdb and then import <http://www.weewx.com/docs/utilities.htm#Importing_from_Weather_Underground> my Weather Underground data?
