My major pet peeves:

Packages that are dead wrong.
... and most are.

Double counting die capacitance in with package
capacitance.

Ramps and Waveform tables created at high load resistance.

Min and Max waveform tables created at nominal voltage.

IV curves which don't pass through the origin.

Extracted parameters at typical corner only.

Loading that does not match the data sheet parameters.

... etc ... etc....
