an new analysis report is compared with an old one (*.html.save).
The size of the diff is used to decide whether to upload the new report or not, whether someting has changed or not.
OSM Data time stamp and the AREAs time stamp always differ, so the size is always > 0.
Do not take the size of the diff (104, 200, 204, ...) to decide this.
Do take the number of lines in the diff file (4 or 6).
4 if the overpass query is based on poly(...) - no AREA time stamp information
6 if the overpass query is based on boundary information - including AREA time stamp information
A difference can be assumed if the number of lines is larger than 4 or 6
Example including boundary information
