Well that screen shot I posted is the default settings for the Report file and that is currently the only permanent record. It is only a suggestion to expand the information recorded if you want to have more detail available at this point in time.
What is displayed in the Statistics > Realtime data, is as it says realtime live data, which presumably is a small buffer of data which is overwritten as it fills and is displayed.
As an avast user, personally I find the whole Statistics section to be very lacking in detailed information. Generally the only time I venture in there is if someone mentions it in the forums.
My report file suggestion is a work around - choose it or forget it - your choice.
