@Scholar,
Sorry, as I see it, none of the so-called evidence you present lifts the secondary fulfilment theory above speculation or indicates that Daniel 4 is about 1914.
Are you suggesting that Jesus really knew the timing of his parousia based on Daniel 4 but just did not know how to express it because the year 1914 is "tabulated in a very different calendrical system"?
Let me suggest that your inability to find a NonJW scholar that sees a dual fulfillment to Daniel 4 .... is because it is simply not supported by the text. It's just another example of WTS eisegesis
Besides, as I see it, Jesus was enthroned in the first century CE.
