GOSU.AI offers details aftermatch stats
It's a pitty but PUBG still doesn't have any aftermatch statistics - the only thing you can do now is watch your death or spectate the rest of game, quite a modest set for such a complicated game.
GOSU.AI offers details statistics on all of your matches: damage given/taken, accuracy, headshot percentage, succesfull shooting distance and damage distribution per body parts. See the screenshot below
The only thing you need to do is add their bot to steam and follow its easy instructions, the rest would be done by the service. Unfortunately there are some restrictions at the moment and you wouldn't be able to receive the statistics immidiately - you'll have to queue for a little bit, but it's totally worth it. This service has impressed Brendan Greene himself.
Earlier the authors of the service has shared some interesting statistics based on player matches.
