Completed Work not matching between Burnup Chart and table

[Robert Biuk-Aghai]

I have often (but not always) observed that the number shown for completed work in the Burnup Chart of a completed sprint doesn't match the number shown in the table below the chart.

Example burnup chart showing 113 story points of completed work at the end of the sprint:

And here the corresponding table showing 100 story points of completed work at the end of the sprint:

So, which one is right: 113 or 100 story points of completed work? And why is there a mismatch between the two?
