I haven't been booted in my last 27 games. How did my boot rate just jump up to 7%?

Check your past games, you must have accidentally booted somewhere....

Perhaps QM games or a RT tournament?

Boot percent is based on of your last 100 games. Check your past games again. Chances are you were invited to a game automatically (using Quickmatch, has QM in game title) and you got booted. To disable it, go to Multiplayer > Quickmatch > untick "Invite me to multi-day games".

Nope, according to that not in my last 27. In my last 100 according to that, I've only been booted 4 times (3 being multi-day tournaments, I've learned not to join those anymore). Is there a way to contest boot rates?

No, it just counts how many boots you had in your last 100 games.

Maybe you could have been booted multiple times from the same game?
I dont know if those count as 1 or as multiple boots...

Stats on profile page may be up to 30 mins out of date.

I also already have that box unticked

Maybe it is just I got booted multiple times from one game. I don't remember that happening, but that seems like the most logical option. Thanks!

Still says 7% so wasn't something on the server end. When you get booted and turn into an AI you don't get a notification saying so. Still says you are still playing, even though you may be a human turned into AI, and that counts as being booted.

Wow, thanks Dan!
I never knew that about AI-takeovers. :o
