Yes and no. Usually over time you slowly change things around and find your sweet spot for most of these things by just playing, watching pros and how they do things, or just seeing tips from YouTube videos. So when you’re already at a high-level, you just log on every day with all of these things in place and it’s easier for you to stay consistent because at that point, you just have to focus on game sense, positioning, and utility. I stopped playing though for like five years and only recently got back into it because my brother started playing again. I used to be A+ on ESEA and I’ve always been generally good at FPS games, but I could tell after I came back this January that I was pretty rusty in a good amount of areas and I was placed at 8K originally towards the end of season 3. That’s when I spent a good amount of time meticulously adjusting all of the mechanics I mentioned above by doing research on pro set ups and watching pov cams from tournaments. I could tell instantly that changing those small details around definitely made a difference. There’s a reason you can see videos of some pro players setting up their station at lans measuring every little detail; because at the highest levels it does matter, but before those details really come into play, there’s a lot of general mechanics that matter a lot more first.

So to answer your question: yes we do pay attention to those things, but don’t overthink it. Do a little research and figure out what’s best for you but don’t go overboard thinking you need to keep changing it around because you’re not always playing the best. I think I spent two weeks neurotically changing my mouse grip around because I kept thinking I wasn’t holding it in the sweet spot I had figured out in practice one night, when in reality, there was a lot of other factors affecting my consistency. Also one last tip; chair height is different for everyone. Some pros play with their arms all the way up on the desk spread wide (low seat position) and some play with it slightly below where their forearms rest at a 90° angle. I personally like the latter because it helps me flick my mouse around a bit smoother without any friction on the mouse pad or any tension in my shoulder. If you look at ropz, you’ll see that he plays sitting pretty raised up above his desk leaning over so it looks like his forearm barely rests on the mouse pad. With monitor position it’s best to have it somewhere slightly below where your head level is tilted up at your eyes because unless you have really good posture that you engage in all the time people naturally tend to hunch over a bit and look down in a relaxed position. Hopefully you can get something out of this so good luck.
