Is that loss per week? If so, it looks very good to me. There are two weeks(?) that have less than 1 pound, one over one pound, and the rest are over two pounds.
The same reason I love the opening page of DietPower because it shows your weight on a graph. Since I don't enter my weight on any day but my weigh-in, it has flat areas and then drops. But I love seeing that it is a downhill slope.
