9lb is brill! But I know what you mean, when I started LL everyone was losing 10-12 lbs and I only lost 6lb so felt really dejected and it almost caused me to re-think the diet. Despite that I carried on and lost over 3 stone.
everyone is different but generally if you compare people who are like for like weights the weight loss averages out the same.
im only on day 2 of S&S but finding the packs so far better then LL and the fact you can have a bit of milk and veg
good luck, it's a great start
