Its so weird, because my last lesson was literally giving me crap about my distances. It almost made me cry, because I thought I was solid on it.
My rule of thumb is when in doubt, push harder, just because I can take a jump huge and sit it comfortably but if she chips in I get all screwed up. She doesn't choose good distances on her own. When I let her do that every single jump is deep or wide. I can usually just tell when the jump is going to be awkward, then I usually just ask for it to be big rather than small. I wish I could get that one trick that fixes it. You know how things like this work- You can't figure it out but then one little thing gets it right for you. I need that.
