i am confused, how did people skip ar 9 and go straight to 10 it seem like going from normal to insane... just you cant
also if ar 10 is faster how can someone not read a slower map that just doesnt even make senses
Well, let me explain it a bit this way.
Approach Rate 10 has an MS value of 450. That means it takes 450 milliseconds for the precise activation frame to appear after the circle pops onto your screen. The average reflex time of a human for visual cues is a little over 200ms. So let's say you are really focused on playing HD/HR at AR10. Your reaction time to circles appearing on screen is likely to be right at about 200ms. This gives you 250ms to get to the circle and press your activation key (tap, X, click, whatever button you use). Human motor reflex (how long it takes for your hand to react to seeing the circle and move the pen/mouse) also takes about 200ms. Once you put the two reflex timings together, they tend to add up nicely to around 400-450, which is why AR10 feels so smooth and natural. AR10.33 is right at 400ms, so if you are feeling really in-tune with your focus, this will also flow quite naturally (very common for DT players, given that AR9 maps are AR10.33 with DT). Anything under 400ms (AR10.87 and AR11), starts to get more difficult again, as reflexes tend to struggle to keep up and mental exhaustion starts to kick in. This is why I find HR so very easy to read, is because it allows me to use a very relaxed, controlled reflex to play the map, and honestly requires almost zero reading. Once you play enough patterns in osu, and you play for long enough, your fingers start to go autopilot, and you can focus 100% on your accuracy.
Things under AR10 require two things once you have become adjusted to the nature of AR10. They require that you *visually* read the map differently, and they require you to look at smaller sections of the screen at one time. When you play AR10, you can look in general areas of the screen without ever directly looking at a note, and that will absolutely provide you with enough information. With lower ARs, you have to try and tune out other things that are going on in the map. Otherwise, your brain will go on information overload like mine, and reading will become a lot harder. This is where reading things like colors, numbers, and approach circles come in handy. Actually reading a map is not that easy, and I am no good at it. There are other players who could offer your way more advice on how to learn and practice (other than the usual "lol just play huehue"), so I will not try to teach something that I do not know.
I am not going to get into the audio aspect of reading, because my post is focused on only visual reading and why visual reading is the way it is in terms of how the body works
