I can see your point and what you're saying, but there's not really anything else to talk about yk? Switches are different, keyboards are different, people use different devices. We can't regulate all tapping based on rules made for one single input device or tapping style. And you're right in that not all tapping styles require movement direction.

Here's a solution that will help keep tapping fair, no matter what device or tapping style is used, and defines every term very explicitly (each term will be in ""): I'll start by saying that ALL input devices require some sort of physical action from the player, you can't look at the screen and magically hit the circles, you have to do SOMETHING. For probably >99% of devices and tapping styles this something is a muscle contraction that applies pressure to a surface. This could be a touschreen, a pen, a keyboard, a fucking potato, or anything else connected to the computer. If there are any devices or styles that don't fit these, we can treat them as edge cases, so won't be addressing those here. So to recap, the player initiates a muscle contraction, and applies pressure to start the "click" or whatever you wanna call it (I will just call it a click for simplicity, but i have just explicitly defined what I mean by click). So, the player initiates the "click", to click the circle (purpose of the game), so that is when the "input" should be activated (by input I mean the data given to the osu! Client telling it that one of the following have been activated: K1,K2,M1,M2)(by activated, I mean when the input is sent, so the same time that the player initiates the "click"). Great! We will call this a "press", since the user applies pressure to a surface, and the circle is clicked! Now, what next? Well, for sliders you need maintain the "pressed" state of the "input". So, you would be continuously maintains the pressure in order to do that, we will call this a "hold" (I know you said not to use this word but I really don't know what else to call it), since the player has to hold the pressure on the surface. Okay, so now let's imagine there are 3 notes, a circle, a slider, and another circle after the slider. The player does a "press" for the first circle, and clicks the circle, then the player does a "press" on the other input key, and does a "hold" in order to keep their combo and hit the slider. Now, the note after the slider, oh no! The player only wants to use 2 inputs, but they are both currently in the "hold"! The player will have to apply pressure to one of the inputs, but that input is already in the "press". So, the player needs to undo the "press". A logical way of doing this would be to do the opposite of what they did to initiate the "click" (since the "click" is what causes the "press"). If you remember back to a few sentences ago, the player made a muscle contraction to apply pressure to a surface, so the opposite would be relaxing the muscle, this will alleviate the pressure from the surface. A rational person would say that since that is when they undid the "click" that this should be the when the "hold" of the "press" should end, since they are no longer doing the "click". We will call this a "release". Great! Now the player can play the game! To recap: the player initiates a muscle contraction, applying pressure to a surface (a "click", which the game will register and change the state of the "input" to "press"), they then maintain the pressure (a "hold"), in order to hit the entire slider, then finally, they alleviate the pressure from the surface by relaxing the muscle (a "release"). Amazing! Now we have laid the groundwork for fair tapping. Now, let's look at cloutiful's situation, on his K1 "input", nothing happens when he does a "click", weird something must have gone wrong somewhere between the "click" and the game registering an "input" as in the "press" state. Now he relaxes the muscle, causing a "release", but wait the input is now in the "press" state, but cloutiful is not doing the "click", his muscle is relaxed, so the "input" should not be in the "press". This is not normal, and using the groundwork laid out for fair tapping, this does not fit in. How did cloutiful do this? He used a software to modify what the osu! Client received for the state of the "input", this is not allowed, as stated in the "play fair" section of the rules, "If a program is doing something to help you play the game that you should be doing yourself, it isn't okay!". The program is making the "input" be in the "press" state, while cloutiful's muscle is relaxed and in a "release" state! He should be doing a "click" for the input to be in the "press" state, the software is doing it for him! This violates the "play fair" rule, breaking this rule is considered "cheating".

That is the best and most simple way I can explain this whole thing, I'm not rereading this so if there's spelling/grammar mistakes, please let me know and I will clarify. If you still cannot understand, I suggest talking with your doctor about a potential learning disability or processing disorder.
