Looks like the starting dot and ending arrow aren't showing up on the images anymore, at least for me.
By the way, the elements from my list are in the default order as they appear in the model: Top left, bottom right, top right, bottom left. (All except for the Knowledge variation, where I accidentally put Process before Result.) I think one could probably explore any quad of elements and relate it to the Variation involved. So, really, the default elements under each variation might better be seen as suggestions to get the imagination going.
As Jim pointed out, as long as all the higher level points are accurate, there's no need to sweat the small stuff.
