You might consider expanding this video to include the calculations involving the attributes. Put that part as the 2nd half, so if people aren't interested in that, they can stop watching, but for those who do like the math behind it, and how the calculated scores are figured, it would make the video that much more valuable.
I do love how you put the video together, however. Very clear and articulate, and it is easy for both new and veteran viewers to understand. Being a native English speaker, I cannot be sure, but it also seems to me that you keep the language simple enough that those using English as a 2nd or 3rd language would also have no real trouble grasping your points, well done!
