You're missing the point. This is straight math.How do you know? UFO's don't appear that often. And by the time you see it, you don't have time to point your phone at it to take a picture. 78 good photos is about right.Not to mention the thousands we don't know about.
Say a white apparition has been spotting fluttering by my (extended) family's window at what seems to be hundreds of times in a year, though we have no idea when it will go by.
For the first year, I check the window every few minutes, and I only have my camera with me 10% of that time.
For the second year, all 10 of my family check the window, and we all have cameras 100% of that time.
If I managed to get 10 shots of this 'ghost' in the first year, the math shows that, between us, we will manage to get 100 shots in the second year, just by the fact that our opportunity to take a pic is 100x greater.
The math is inescapable. Few samplings = poor representation (such as a false positive). More samplings = more accurate results (a false positive, if it exists, will be eliminated).
This works the other way too. If I am at the window 100x more often, and I see a white ghost less often, that strongly indicates that the sightings are a false positive.
Let me re-iterate: if - as the number data points increase (in this case - cameras-in-hands) - the results do not go up - or worse go down - that is a very strong indicator that the original sparse data was finding a false positive.
So, profoundly fewer pics, despite an (orders of magnitude) increase in opportunity, is a strong indicator of false positives.
