Since we don't have access to the home position for all cachers, we use a different method to figure out where people live. The method uses statistical methods to figure out where you are likely to live. This is done by looking at your logs and in what location they are made. Your most recent logs will have a greater weight to detect when people move. If you live very close to a border or travel internationally a lot, this method may have problems. If so, send an email to Project-GC support and we can make a manual fix.
