I completely agree. This is not a scientific test situation at all. This shouldn't be taken as proof that desulfators work. This is just my experience. You are completely right that using a tired battery will bring it back to some extent too.
The reason I do comment, is because the last time I drove the Paseo (about a week ago), it was not holding a 12.7V charge. The battery has been on the desulfator all month long, not just during charging. It stays on the car and runs all the time. The car hasn't been in constant use lately at all. I usually drive it once or twice a week. But, when I first did the alternator disable I was driving the car every day that week and the week after and didn't notice much of a change to the battery during that time.
