I have received no vision or direct revelation but Jehovah has revealed such matters to His Church, Elect, Body of Christ, Christian Congregation, Faithful and Discreet Slave and the 'celebrated WTY scholars by means of Revelation such process involves God's Inspired Word and Holy Spirit.
The date 607 BCE is firmly established, Neo-Babylonian Chronology with some fine-tuning can be utilized in support of that date.
The problem of indecision or uncertainty concerning 586 or 587 BCE is due to the biblical data because the celebrated WT scholars use the same biblical data arriving at a specific calender date, 607 BCE. Your problem is 'methodology' freely admitted to by Rodger's Young's article.
