‘scholar’:
The problem with your opinion and charts comes down to Methodology and that has now been recognized by Chronologists such as Rodger Young who first introduced the term into scholarly journals in his advocacy of 587 BCE by means of the use of Decision Tables Analysis. But again Young fails to account for the Jewish Exile even though he has produced studies on the Jewish Sabbaths and Jubille.
Irrelevant misdirection. Though Young’s method is sound, BM21946 definitively identifies the placement of the first siege relative to Nebuchadnezzar’s reign. Jeremiah 52:28-29 definitively identifies the placement of the final siege relative to the first siege.
The period of 49 years from the destruction of Jerusalem until the Jews’ return does indeed fit very well with the concept of jubilee years and paying off sabbaths from Leviticus though.
