Unsurprisingly from my own experience so far, I see others who actually sit down to take notes find much the same as me (and TyPinOwly). My guess is that people are confused by the rolls that deal no damage, still. They LOOK like misses, but aren't.
There's also a guy on Steam who actually recorded all individual dice over 110 throws on a 65% chance (needed an 8 for a hit).

To sum it up:
71 hits (~64,5% chance to hit) 7 crits (~6,4% chance to crit) 29 misses (~35,5% chance to miss)

In the UI, it does. Attack bonus of 5 vs an AC of 7 (needs to roll a 2) on ADVANTAGE. That said, according to this graph, this exists -- even if you rolled two 1s?? http://media.zerohitpoints.com/images/higherthan.png
