KDA not accurate

I have a 0.5 KDA with 160 kills 153 deaths 35 assists and 32 games how is this possible

I hate it when my kd goes down fast

(K + A/3 - D)/G = KDA. K is kills. A is assists. Divide it by 3. D is deaths. G is number of games played. KDA is not global - it’s calculated for each specific play list.

160 + 11.6 - 153 / 32 = 0.58

I have to guess that it rounds down.
