Another useless post.

I have an old UL standard for Snap Switches (like a wall switch).

For AC only switches the tests include the following - at rated voltage:
10,000 operations at rated current
10,000 operations at rated current and power factor around 0.8
10,000 operations at rated current controlling incandescent loads
100 operations at 4.8x rated current and power factor around 0.5

At the end of all these operations the switch has to still be functional.

How is that not "real-world"?
