In what ways might the triangulation be "incorrect"

[cmann1]

The readme states:

sacrificing triangulation quality for raw speed and simplicity

and

After getting a triangulation, you can verify its correctness

In what ways would the triangulation quality be lower or incorrect?

I think it would be useful to have a description and maybe even a table of visual comparisons between output from this library and output from other libraries in the project's readme.
