Data as in numbers? No. Video clips from my gameplay and nearly everyone else's gameplay will prove that red bar connections and laggy connections on the whole have the advantage.

Unfortunately visual evidence in a game isn't enough, especially since we aren't seeing it from the laggers prospective. Data however, which bungie has, cannot be contested. This leads me to believe that they could be having just as much trouble. I mean, I feel for you and I'm sure people purposefully manipulate their networks. But the main issue is P2P matchmaking. Dedicated servers would help everything, making it easier to distinguish someone with an average connection to someone that is purposefully manipulating their network. I have a red bar sometimes, likely when im connected to a host halfway across the world or a host who also has an average connection. I can tell you that it is a chore to keep up, and most times when I experience this my kills don't register for about 3 seconds. Or alternatively I'll peek out for a snipe and go back around the corner to hide and a few seconds later I'll drop dead from a sniper round to the face. In the end, the only ones who can 100% judge a cheater is bungie, but something tells me its actually their P2P matchmaking system that's at fault. Of course if you see a -blam!- tard disappearing and reappearing he's probably cheating and you should report him. Another problem is when bungie sold the game to many year one players the requirements for a excellent internet connection was not something that existed. In fact i don't think the case says to this day that you must have a certain speed to run this game properly. If I'm wrong feel free to call me out, if im right its actually bungies fault for being to lazy to craft dedicated servers.
