If you are going more stalks than that for your level 2 without having an opportunity to cull what is probably wrong is you haven't chosen your time or place very well. Of course you might be unlucky or not good enough but if that's the case your AW should be telling you not blindly slogging away at it.
Thats the point I was trying to make really. As an AW myself I am always honest with people and actually question them considerably before they even come for a stalk just to make sure that the expectations from both angles are realistic.
