Downloading the data works as you described above.
My first ‘missing’ month of data from WU contains 87,343 lines in 62010lg.txt! What appears to be good data uploaded every 5 minutes (but not always exactly on the ‘5’) is on WU for 30 days, but that’s not the way it shown in the attached - only 18 days and funky numbers with a lot missing. I can zip and email you the lg.txt if you like.
Thanks for the extra work on this - most appreciated.
