Actually it's because in OOXML, the border size is measured in 1/8th of a
point. Citing description of "sz" attribute of CT_Border (ECMA-376 Part 1 sect.
17.3.4):
<span class="quote">> If the border style (val attribute) specifies a line border, the width of this border is

The type of the attribute is ST_EighthPointMeasure, which is an unsigned
integer.
So a value of 0.80 pt is rightfully brought to the closest multiple of 1/8th of
a point (sz=6, i.e. 0.75 pt). The other possible value (sz=7) is 0.875 pt,
which is less accurate.</pre>
