I think the positions do not matter, as long as its comfortable.
Take a look a hockey players- they all have different shoulder and elbow positions but all have one thing in common, and that's using what feels most comfortable for them. Like someone already stated you may be wearing the heel of your stick because its too long. I personally play with a 5.5-6 lie stick to my chin ON skates. I'd prefer a 5 but haven't found a curve I like in that lie, so I stick with what feels best.
If you're really worried (which you shouldn't be) get someone to take a picture when you are on the ice. Video works best. Then watch it and see whether you need to cut your stick, move to a lower lie, or do nothing. Video is an athlete's best friend. Don't post it here unless you really want to- in that case you may need one of them Japanese censors
