All that you are doing with the figuresis manipulatiing the data to support false chronology. We simply do not what methods were used at the time and this is a bone of contention amongst scholars. Whatever the case your method is unhistorical so the manipulation of figure ignore the plain stated facts of scripture that it was only in Jehoiakim's fourth year coinciding with Neb's first which is believed to be his accession year. So the event of Daniel 1:1 does not synchronize with Jeremiah 25:1Neb's first year is said to be his accession year which means Jehoiakim's third year of Daniel must precede Neb's events in Jeremiah 25:1. Your tabulation of the data is well known to me but it looks on paper but it is an illusion, a conjurer's trick.
As celebrated WT scholars have told you that one must get the history right first before the chronology.
