For beginners and medium beginners, the attachment to Rating can be a waste of time and a place where frustrations reside, the rating is not the end in itself, it is a means, it serves as a beacon, as a North to know where you are. Each platform has its peculiarities despite similar metrics, taking chess .com as an example is a little more complicated, as the fact that there is no default initial rating on it, there is a mixture of Ratings, as many medium and strong players insist on starting as beginners/novices for the sake of challenge, it is worth remembering that a player who starts with 400 points (new in Chess) will need more or less 20 consecutive wins if he faces opponents always from the same lane to beat 1400, and with that the gains and losses will be smaller with each game and if for some reason it is lost in that interval, the rise will take longer as it will stabilize at a Rating below the player's real strength and this explains a lot how much there is a relatively strong player in the 1400 range /1600 creating a kind of force bubble difficult to break, the self declaration rating on chess.com is somewhat problematic.
That said, the tip is not to care so much about the numerical factor, if you are not succeeding, you need to ask yourself questions, and see what your goals, means and ways of achieving them are, if you do not study your Rating you will it takes time to go up and if you don't go up even studying, it's because you don't have the game volume for it, it's an inconvenient truth, chess needs practice, study and time, vertical evolution in chess doesn't exist unless you're a genius, so the The fact that having an X or Y Rating becomes a little irrelevant what will say a little better about your strength is the average opponents you have won, so if you beat your 1800 and your winning average is 1500 you are a “ 1500” player who had a peak of 1800, however if he has managed to keep up and raised his average then yes, it's time to celebrate his achievement!
Yes, there is a clear discrepancy in the ratings, as there is no default initial rating, there are many medium and strong players with ratings below their real strength creating rating bubbles, this is clear here.
