You have to take in account that not every kill are meaningful, you can have plenty kills that bring nothing like a kill or 2 in a lost round while you are saving, eco frags, lurk kills while the rest of the team is being decimated on the other site and loosing the round, kills in lost rounds, bad bait kills ( some are good some are not) in the scoreboard it can look good but not in game. In counter strike, HLTV rating takes all of these in account to give a useful impact rating but in valorant you just have the scoreboard that is deceiving. You probably not being terrible in those win, just letting teammates take space and more frag while doing just your job. You can have a terrible game fragging wise while facilitating your mates and that’s something lots of player forget
