Seat of their power - read it carefully. They change the number 3 into 11 by changing what they are talking about. Starts off as Jehoiakim's rulership then switches to Jehoiakim vassal service to Nebuchadnezzar. Its a different number 3! Like 3 apples are different to 3 pears. 1914 rests on this and Dan 2:1 (a different but equally silly trick).

The expression “for three years” is of special interest to us, for the opening words of Daniel read: “In the third year of the kingship of Jehoiakim the king of Judah, Nebuchadnezzar the king of Babylon came to Jerusalem and proceeded to lay siege to it.” (Daniel 1:1)

It was this event that Daniel the prophet writes about: “In the third year of the kingship of Jehoiakim the king of Judah, Nebuchadnezzar the king of Babylon came to Jerusalem and proceeded to lay siege to it.” (Dan. 1:1) This “third year” of vassalage to Babylon would be the eleventh year of Jehoiakim’s entire reign and would be due to end on Adar 29, or March 19, 617 B.C.E. He died before he lived out the end of this eleventh year.
