Extremely sorry for late response bro, I was caught up in few things.
1st account 3.9-4k
2nd account 3.7-3.8k
1st account has better chances of crossing 4k than the other one. 1st account may be almost 200-300 point better than the 2nd one. If you analyse both of your accounts yourself, you can easily point out the difference,i.e., KDA and number of deaths. Improve both the aspects as much as you can and you’ll see some good difference.
