USPS tracking and USPS delivery confirmation are two different services at two different prices.

Delivery confirmation is good when you sell on ebay and want to avoid a person saying "I didn't get it" and getting their money back through paypal, it isn't intended to be used as door to door tracking.

Tracking, which costs more, will track the package at each stop, give time stamps etc. and also confirm delivery at the end of the trip.

I just received an important package through FEDEX over night an the tracking number allowed me to watch the package, in real time as it made it to the terminal, was loaded on the truck and then marked as in destination. Scheduled time was 12:00 noon delivery, it arrived at around 11:30. I guess I'm one of the lucky ones as I use these services almost daily and never have any problems. *knock on wood
