My grown up opinion is that if your interest is simply academic, it's interesting, but you should never knowingly exceed the gauge other than in a life-threatening situation and should disclose it every time.
If your purpose is at all to conceive of scenarios where you might, at some time in the future, use your freedom of choice as a pilot in command to pull more MAP than permitted in what you consider to be a practical and safe manner, please have the decency to leave a list of machine names you use so the rest of us can have the freedom of choice to avoid them.
That's not a petty aspersion, just a statement of fact that a lot of us who rent aircraft depend on the fact that everyone before us has acted according to the POH for their own and their passengers safety.
