Don't be ignorant.

It should have been as obvious to you, as it was to me just by reading your post, that one game had 100,000,000 plays on it, subsequently hammering the playfield smooth as glass, while the other game only had 5-10 plays on it, hence the moon craters.

Plus we've recently learned that all pinball playfields, since the beginning of time, come from the same manufacturer, who cuts each playfield out of a single tree.

If I'm wrong about the above, then I suggest you look into cornea transplants, or an inpatient plan with optometrist, as I'm never wrong.

Well, based on the irrefutable facts previously presented, one must conclude that both the equipment used to test playfield hardness, and the person performing the test, are indeed defective.

The ONLY other possible explanation is that somebody nefariously just posted completely made up hardness test results to help instigate yet another subject for pinsiders to argue about.
