You are probably correct that the SECULAR WEIGHT OF EVIDENCE favours 586/587 but this view is something I have recognized in many of my earlier postings. The simple fact of the matter is that I believe in the BIBLICAL WEIGHT OF EVIDENCE which favours 607. I also understand that secular chronology is far too complex and uncertain which leads to many conflicting opinions amongst scholars despite the fact that there are many astronomical fixed dates . Whereupon, there are very few biblical dates if any, apart from the Fall of Babylon that enjoys complete consensus. The calculation of 607 is well based on historical evidence as you well know and provides an immediate and direct coputation to the Fall of Jerusalem.
In contrast, Jewish biblical chronology is very complex and also suffers the major difficulty of wide opinion. This is well highlighted in the study by Jewish chronoligist Eliexer Shulman in his 'The Sequence of Events in the Old Testament', 1987. This publication presents three seventy year periods, each of which has a different beginning and end. Namely:
Seventy years of the kingdom of Babylon
Seventy years of the Babylonian Exile
Seventy years of Jeruslalem's desolation
