...My 120g year old male ball python is about twice as thick as my 5 year old female corn snake! :]
What's going on with him? That is REALLY thin for a yearling
To the OP: Your snake is just little right now and so I would stick to the 10-15% amount until it gets a little older and has a little more weight on him.
