What do all the stats mean in the PUG player stats? I'm very confused about what RWS means, and I haven't found any place that defines what all the acronyms and such mean. If someone could please explain such, that would be very helpful.

RWS = Round Win Share, how much you contribute to a round

KDR: Kill/Death ratio
Record(W - T - L): Wins - Ties - Losses
Accuracy %: How accurate you are(ie percentage of your shots that actually hit the enemy)
Headshot %: The ratio of your shots that are headshots
ADR: Average Damage per Round
FPR: Frags per Rounds
I think that should be it..
Thank you very much, that answered my question completely.
