The 'Chinese' Theory: For and Against

[eggyk]

All I can say is that the SPS seems to correspond to the SBJ almost word-for-word. 

I'm not sure that can be said. At best, you've found 1 word that roughly lines up in the SPS and SBJ. For all we know, there was another recipe in the SBJ of roughly the same length, with roughly the same distribution of 主. 

If you could present a 2nd or 3rd word which also nicely lines up with the SBJ, even then you could only say that "The SPS seems to roughly match the format of the SBJ, with a few common words having similar positions in each"

Its just as possible that a recipe entirely unrelated to the SBJ, on a completely different subject, could also have the same relative positions of the phrase "it is used to" as is found for daiin in the SPS.
