This is indeed a good resource. Something that a lot of people dont realise is that the flexing of the shaft around the nodes can comlicate some tuning methods. Specifically, when a shaft that is minnowing is used in a paper tune, it can appear to be untuned when it in fact is. You only need to know that the nodes are passing through the same spot, and if the nodes are going through the same spot (Assuming youve got a correctly spined arrow), then the tip and fletches will logically go through the same spot as well (that is, a different line to the nodes due to the minnow). How to get around this? If youre going to paper tune, get some of the missus's brightest red lip stick and put it on the tip of the arrow before running it through the bow. That way, youll get the red dot on the paper and the cross tear that will highlight where the tip and fletches went.
If the dot and the cross are aligned but there is still a tear away from the dot/x, then you might have spine issues - check your arrow spine.
