If you're shooting a 70# bow, you should be at a .340. A .400 is way under spined. If your rest is all the way to the left your center shot has to be way off. Don't let the paper tune fool you. It's possible to manipulate the paper to be correct but your rest we well off.
Get the .340 back out and play with it. You should be able to get your center shot and go from there.
Any more questions just ask.
