Which is great, because she can easily import all her previous records (the script does it all automatically, you just have to specify your WU ID and months to import). Of course you can always start with blank database, but obviously it is not very interesting in the first couple of weeks because all your record values, monthly comparisons, annual comparisons etc. are useless.
If however you start with 2yrs of data already, everything is showing interesting information straight away. And then she can set up the regular 5 minute updates using the script I made today, which uses info from WU. And that will be gradually adding data to the already existing db.
