Not all edits increase the amount of bytes. For example, if you deleted whatever you wrote previously, which added 151 bytes, you'd get -151 instead. If you didn't delete it but replaced it with a shorter text, it might say -34, or -51, depending on its length. In other words, you can pretty much ignore that number!
