It is 100% dependant on the trueness of the hub, not the hole. All the hole does is locate the prop to the center of the shaft and provide a location for the nut to clamp the prop to the hub. To check tracking, install the prop and tighten it. If it's off, you can sand the back of the hub and rebalance. For future reference, do that first before balancing since you may need to remove material to get it right.
