You know that is an excellent question! I have assumed it was 10% of your starting weight, but maybe I've been wrong. Also, I am a slow loser, and I have found out through posts on this forum that the 10% is not a hard and fast rule and you are NOT failing if you don't reach this during induction.

Remember, everyone is different. I believe being persistant and consistent are the keys. Hang in there and it WILL work!
