I can understand you not wanting to change the method you have been using, but if it can be improved, maybe you should give it some consideration??? As to the pics you reference, they demonstrate or indicate that the rift grain flames of the shafts should point towards the arrow head, on the top of the arrow, as it sits on the shelf, as I have been attempting to explain.
With the picture from the book you just posted, only the bottom right photo indicates in which direction the arrow head is to be (to the left). The grain of the arrow in this picture shows the rift flames facing towards the head.
In TBB, on page 230, there is a stick figure drawing re spine. But the facing page 231, shows an arrow sitting on a grain scale. The rift grain flames are visible in this picture, and they too, are oriented so as to face the arrow head on the top of the shaft (we can tell it is the top of shaft due to the nock and nock indicator).
So, once again, I am thinking, if these pictures of the arrow rift grain are how you orient your shafts, then we are in agreement. From your other writings in this thread, though, I got the impression you were advocating that the rift grain flames on the top of the shaft should be pointing to the nock end of the arrow - and if this is what you believe, then not only do we disagree, but I also believe you are mis-understanding the pictures and diagrams you have drawn attention to.
