I don't think it's helpful to compare yourself with other people as there as so many factors that affect your weight loss other than just what you put in your mouth. I've seen people lose a stone in a week, and others that take the more scenic route losing half a pound or a pound a week. You don't want to put yourself under the extra pressure of having to compete with people who have big weight losses. All this does is mess with your head and bring you down, making you more likely to come off plan. It comes off in its own sweet time and all you can do is try and maximise the likelihood that it will come off by following the SW rules of sticking to plan, eating your HEs and syns, having lots of variety in your foods and menu, and if possible also doing some exercise.
