This same time line says the Babylonian Captivity was "422 BCE".
14 x your figure for a "generation" 67.21 == 940.94, as you said.
941-422 = 519.
So EITHER "the Anointed" appeared in the first quarter of the 6th century of the Common Era
OR one of the figures is wrong.
Try this: 422/14 = 30.14 which is less than half of three score and ten, but that puts us at 1 AD.
There's a problem.
As I indicated in my first post on the subject Psalm 90 is a starting point.
Matthew 1:17 So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon unto Christ are fourteen generations.

The names with the asterisk are listed in the Old Testament but left out of Matthew. Find a scholar that can explain that if you can.
Does the Bible contradict itself? Of course the answer is no but I will let you study to find for yourself the answers with the help of the Holy Spirit.
There are other passages to establish the length of a generation but I will allow you to do your own study and come to your own conclusions.
I think you will find that Jesus is the 66th generation since Adam btw. 66x70=4620years. Then add the 2011 years since and you get 6631 years or the appox. years since the creation.
