Another example of problems with the JW chronology for the kings of Israel is that the gap between their chronology and reality increases to 68 years by the time of Rehoboam and Jeroboam. (This specific duration is deliberately manufactured to shift the end of Ezekiel's '390 years' to the fall of Jerusalem, though that period should end only once they'd 'atoned for their sins'. The difference of 68 years corresponds to the period from the JW's alleged fall of Jerusalem until the subsequent fall of the Babylonian empire in 539.)
This causes problems with correlating their chronology with secular history. For example, Assyrian inscriptions indicate that Shalmaneser III was contemporaneous with king Ahab, at the Battle of Karkar. The date of the battle is determined by secular historians as being in 853 B.C.E., based on astronomical observations.
In the JW chronology, there are 61 years between the end of Ahab's reign and the beginning of Shalmaneser's. Insight devotes more than a full page trying to debunk the fact that Ahab and Shalmaneser's reigns overlapped. However, in reality, Ahab was indeed contemporaneous with Shalmaneser III.
As seen in the chart I provided earlier, in 853 B.C.E. Ahab was co-regent with Jehoram, even though I gave no consideration to Shalmaneser's reign when determining the Bible's chronology.
