Yeah, but he usually does a short 10 bullet spray. He taps only when he's jiggle peeking and can't safely do it while using 2 bullets nor would the second bullet have any type of accuracy.
The most effective thing to do rn is, instead of 2 bullet bursts, train your muscles to be able to perfectly control your first 10 bullets. Really, it's very easy once you get used to it. Perfecting it is harder than a standard 2 bullet burst but the results are worth it as you'd be getting the same accuracy as those 2 bullet bursts yet not having to reset recoil.
Only way to get to the top now is to innovate. If you copy others you'll never get far, the reason NiKo, rain, coldzera, fer and s1mple are currently top 5 is for no other reason than the fact that they have a quite unique aim pattern. None of them use the simple 'far range tap midrange burst short range spray' guide.
