HI
how can the real time updating values of longitude and latitude from a gps
reciever being shown in QGIS Live GPS tracking tool can be stored in a database

Did you set a CRS (for this project or as default for new layers) before

An instant thought, which is probably wrong. Could you use the vector tools to
generate centroid points and count those?
Probably only going to work of the polygons are more-or-less regular.
Do you know what is causing the difference in the count? Is it including
