I know that it is not right to discuss other theories in the AOM section but one way to strengthen your thesis is discuss other theories - or parts of them that might contradict one of your propositions. This means if one theory explains things better than another , then it is probably the correct one , at least it seems that way until a better one comes along.
Regarding the course levels. The obliquity is probably encoded, but there are others ideas - or info encoded at the same time. For example the atomic weight of Sodium is 23. I have looked into this type of info extensively.
