I can confirm there are some random errors like truncations, fields shifted or missing.
Another problem is that if you download a daily raw log just the day after in the early morning , records reported stops a couple of hours before midnight. I'll explain better with an example:
today is the early morning of the 9 march and I download the raw report of the 8 march: looking at the timestamp
field the last record reported is around the 21PM; if I reload the same raw log of the 8 march in the evening of the 9 march now the last record timestamp is around midnight.
It looks like the raw report is published and downloadable, but still in progress.
To analyze and get statistic from the raw reports I've created a Filemaker database, so it's easier to detect errors.
Another thing of the new reporting that it should be improved is the storefront because it does not report the real geographical location of the iTunes U user. There are users from different countries that select other or wrong iTunes Client Country Store instead of the real geographical locations. I've compared this using the IP number field of the reports and confirmed by the daily log raw reports that are still available from the iTunes U "dz" sites via "GetDailyReportLogs" web service ( see iTunes U Administration Guide for Private Site).
I suppose that storefront is used instead of the real IP address because not all countries ara available in iTunes U Store or probably for privacy reasons, but it would be nice if somebody could confirm this.
