 So you have no way as a layperson to weigh that refrigerator. Well, you have no way to collect it to even weigh it and then to put it back in correctly. Right, because it has to be collected so it can be disposed of properly. Well, you have to collect it and find out what you took out. So let's say now it's a 13-ounce system and I pull out 10 ounces. Well, I know I had a leak that leaked 3 ounces. So I find the leak.
