Offset Path with small values (or Inside / Outside strokes) results in skewed lines
Offset Path with small values (in my example it's 0.02 mm) results in skewed lines, compared to original text it's applied to.

A related bug report:
Precision is broken for small strokes with Inside / Outside alignment enabled

Both Inside and Outside modes for stroke generate dynamic hidden compound paths using Offset algorithm, which fails at extra small values.
This is clearly a bug!
Another report, about Offset specifically, exists: http://illustrator.uservoice.com/forums/601447/suggestions/39425959
Would you mind me merging these two, since the nature of the problem is the same? -

This just happened to me as well (that I've noticed).
While working on a logo, I used offset path and only realized today (when the logo wasn't snapping vertically) that the X values didn't match on the verticals. The angle was ever-so-slightly off. I now need to go back and recreate the logo from the earliest stage of that concept and adjust to ensure the measurements are precise.
Here's an image of the early stage where I figured out the offset path caused the issue. I began with the center shape and had used offset path for the outer shape. For the screenshot, I've used the dimension tool to show the difference. Hope this gets fixed soon please as it seems minor, but it can be compounded. Thanks so much.

0.02以下のパスのオフセットを適用すると、
パスの周囲に生成されるオフセットが歪む。
0.03以上では発生しません。

Having a similar issue. Doing an offset smaller than 0.001" results in skewed lines. Offsets 0.001" or larger seem to be okay.

Why this happen? if i put the stroke in the middle works fine but if i put the stroke inside this happens.
