This is new tech and is changing fast. Perhaps by just getting in to LiPo I have no baggage from early adopters, but the facts that over 1C charging will shorten their life span (at least to a significant degree) are slim to come by. Or is a loss of a few % of cycles, if any, a big deal to some? Is it due to fire hazards? I can't see manufacturers promoting a practice that would cause death to their users... well maybe a little bit.
Of course I am still learning a lot, and I don't want to 'fight it out', but the scientist in me wants to see some proof on this, otherwise I will remain skeptical. Maybe another statement that gets credence by sheer repetition. Just like 'warming up your (full sized) car in cold weather' is a hold over from carburetor days, yet I still see it mentioned like it was gospel for modern fuel injected cars.

As it is really not written in stone that you should not charge over 1C but for rc electric users we would usually want more runtime/cycles on our batteries, so we charge at 1C or less. Manufacturers states on some batteries that you can charge over 1C e.g 2-3C which you can but will decrease life/cycle as internal resistance goes up, as they say if your in no rush charge at minimum, but having those higher charging rates are nice when you are in a jam and need it charge fast!!
