not sure how it works i mean i know a little but its seemed very vague to me can someone explain? (Only curious because i got my first 100% KAST ever in ranked)
to add:
K and A is pretty explanatory
Surviving just means carrying over next round (so if you didn't get a kill or die, but survived, this would count)
Trading is usually within either a 3s/5s period where a teammate kills the person who recently killed you.
However, KAST% isn't always a good indicator, since it discredits multi-kills/multi-assists, and disfavor duelists while favoring controllers (very easy to exploit smoke assists or assists like brim stims unlike initiators, which take a bit more effort to get an assist)
And obviously you can't really see how much IGLing impact an IGL has, but neither can other stats
KAST% = (# of rounds where the player secures a kill, assist, survives, or is traded)/(total # of rounds) *100%
