The same is true of SPICE models.

You can run experiments like you did to see how it compares with the
published spec sheets (which is really just a quick "sanity check"), but a
better "proof" would be to compare it with measured data from actual parts.
If you have access to such data, you can compare either in the static (i-v)
domain, the time domain, or hopefully both.

With the experiment you did, make sure the toggle rate is low enough so you
weren't hitting some sort of resonance, which might have made the amplitude
appear larger than normal.

I have seen some "interesting" models from time to time, both SPICE and
IBIS, that did not represent reality.  It's always good to question what you
have.
