Well, the finer the breakdown is, the less chances of getting it right by sheer random choice.
If the breakdown were "How many? 1 to 100?" everyone would get it right.
I've been lucky enough in days long gone to have done similar informal shooting at lots of "junk targets" of opportunity out in the boonies with lots of guns at lots of unknown ranges, so I often have a pretty good idea of what will happen in these polls.
I've been "attacked" by abandoned cars, downed trees, TV sets, water jugs, random rocks, a dime at 100 yards, etc.
I remember setting up the "Great One-Shot Bottlecap Hunt," were we would take turns at trying to hit a bottlecap at say, 50 yards, with our .22s.
This, in similar fashion to and inspired by the annual "Great One-Shop Antelope Hunt" competition that the Governors of Wyoming, Colorado, Utah, and Montana used to engage in before the mass immigration of pantywaists
from back east took place.
However, I admit I have never been attacked by multiple keyboards... thank goodness.
But now I know I can cope with 10 aggressive keyboards with the 7.62 X 39 cartridge.
