You're not saying anything here. "actual instruments". LOL.
But let's play. What did the CR test show? It showed that Apple's new iPhones performed abysmally compared to the Note 3, LG G3, and older iPhone 5. If It were reversed, and the Note 3 and LG G3 were at the bottom of this testing barrel, you'd all be saying how much of a piece of crap Samsung and LG are and how Android sucks and blah blah blah.
The bottom line: this is a controlled test and is NOT conclusive regarding real world performance. But the fact that the new iPhones performed so bad is itself not a good thing.
If there are indeed weak spots in the phone (they didn't apply the primary force to the weak area right inline with the bottom volume button), real world performance of the new iPhones regarding rigidity may not be good. But we still don't know for certain as more data is needed. This is why people's bullcrap arguments that "70 pounds is a lot of force man!" "Ya man!" These comments are useless for two main reasons:
1. First, you have no idea if 70 pounds of force is "a lot" of force. What does this actually mean? You don't really know but you're just saying it.
2. Because the iPhone may have weak spots, it would stand to reason that it would require LESS force than 70 pounds to bend the phone.
And what's also useless is thinking that if you don't put your iPhone in your back pocket, then it won't bend. This is reality: there are so many variables that could cause the iPhone to bend in terms of the way people use mobile devices. Even having it in a large front pocket with tight jeans may stress the phone and cause a bend. We don't know.
