Exactly right! And one person's "small" rat may not be the same as your "small". So it's a good idea to use your best judgment and feed what will not leave a noticeable lump. A weight would help, but isn't really necessary. If your small rat leaves a lump, wait 14 days before feeding and then go down one prey size and go 10 days from that point forward.
