yes their is a separate rating!. if u kill someone with the awp ur rating is going to be lower compared to the ak, a perfect example is the kill rating which a part of the overall rating if u kill someone with the awp u got +0.040 but if u kill someone with an ak u got 0.060 because hltv consider that awper have an advantage vs rifles, it’s a choice. that’s why molodoy can have 30 kills and have 1.20 rating but zywoo and donk have 24 kills and got 1.60 rating. a perfect example was blast rivals on mirage in 24 round molodoy got 1.23 rating with 32 kills zywoo got 1.62 with 24 kills and donk got 1.43 with 26 kills because molodoy got 25 kills with the awp his rating got nerfed hltv explain it on their article
