Not gonna lie I got a bit humbled lately when allocating much more time (left from not playing Apex) to aim training.
In many scenarios there you see like tens of thousands people in a leaderboard and in some cases that figure goes into millions (most popular scenarios you usually see in YT streamers).
My current skill and goal is to be top 10%, at this point my logic goes:
a) I have good enough base before aim training so I could break into top 10% same as I did in Apex (your D4+)
b) I assume that some people above me are cheating (yeah unfortunately even in aim training cheats are possible) or exploiting some mechanics how scenario should not be played yet that yields legit (no cheating just exploiting) results, and some are just better than me
c) in aim training community many tailor settings per scenario that is beneficial yet I don't do that I play with my in-game settings every time to train for in-game performance instead knowing that in some cases it will hurt my score in aim training
Now to the humble part - after like 1+ month of aim training now and reaching my benchmark in basically every task I play for my personal needs / weak and strong points I bumped into what seems to be two legit CS2 pro player videos where they went into aim training to improve their skills and they also showcase actual footage of them doing some of the tasks.
One of the pros is constantly appearing in TOP3 scores, the other one was playing one of my favorite tasks where I have a score around 600, my best is like 609, his score was 890 = 46% better.
And then I realized the fact that even on my good days when I don't miss and hand-eye coordination feels on point I still do pretty slow in comparison to pros / my accuracy is falling if I start aiming faster.
Which just shows that in some cases people are actually insanely better than you, which might seem impossible, at the same time if you spectate those people you would see why not that bs that you see when you spectate hacker squad that clearly has no brain and cursor just flicks onto enemies and what not.
These pros also state that becoming CS now CS2 pro basically takes people approx. 10!!!! years in the game, with some odd exceptions where people have managed to break Tier 1 faster.
So comparing me who plays Apex since 2019 and aim trains for like <200h I guess it makes sense that people with 10 years under their belt can do 46% faster, but those are a few and far apart not like in Apex 1 squad at least in every lobby.
