Here's the thing though:
peak down, one second at the most, and there's nothing wrong with that. Some instructors will tell you that you should never look down and it should always be by feel... but that's not realistic in my opinion and more or less them being nit picky. Now, if you're looking down longer than 1 second and I really mean 1 second... fine, but peaking is totally acceptable.
Like everything in riding, it's going to take a long time for you to pick this up without even thinking about it.
