When they first brought out accuracy in 2017, it was called "CAPS" and they included a graph of average CAPS versus estimated rating.

However, people misunderstood the CAPS score, looking at individual games instead of averages, and it was often used to make cheating accusations. Chess.com revised the system in 2021, lowering the average scores overall similar to grading on a curve and haven't released anything that similar to the above showing correlation of the revised scores with over the board ratings.
This is from the current Help pages:
How is Accuracy in analysis determined?
Each game review shows you an accuracy score, and classifies all of your moves. But how are the accuracy and classifications decided?
Accuracy Scores
Your Accuracy is a measurement of how closely you played to what the computer has determined to be the best possible play against your opponent's specific moves. The closer you are to 100, the closer you are to 'perfect' play, as determined by the engine.
Chess.com’s Accuracy score is now powered by “CAPS2”, an improved version of the original Chess.com “CAPS” (Computer Accuracy Precision Score) algorithm.
Moves are still compared against the top engine recommendations, but the math on how these are calculated has changed. Why? Well, most chess players - even low-rated ones - make a lot of the best moves!
Previously, CAPS (v1) looked to create a 0-100 band within the normal human player range. So, scoring perhaps 40% “Best” moves, which is very low, was equal to single-digits on CAPS. And, scoring a very high number of “Best” moves, but not a perfect game, was often rated 99.9 on CAPS, even though it wasn’t played perfectly.
This made some people feel bad (on the low end), and led to a lot of cheating allegations (on the high end). The new Accuracy scores, based on CAPS2, replicate the feeling of being graded on a test in school.
You will notice that the majority of scores now fall mostly be between 50 and 95, which provides a more intuitive understanding of how accurately you played in your game.
The image below shows Accuracy scores from CAPS and CAPS2 for players rated between 1000 and 1500.

To me, the above graph shows data for players rated between 1000 and 1500. Grading on a curve results in about 50% of all games scoring between 70% and 90%. I would think that getting on the high side of 80 is a very good goal for players in this range.
I see that you are currently rated 1056 and have had an average accuracy of 74.3% over the last two months. I would guess that an increase in your average above 75% and moving closer to 80% would be reflective of a continued increase in your rating.
I don't think anyone has assembled the data on what the average game between 2000's looks like from an accuracy score viewpoint.
So my "accuracy" is normally in the 70's. I've cracked 80 a few times and been in the 60's many times as well. I'd be interested to hear some perspective on this. If two players with ratings of 2000 play each other, will their accuracies both be 90, or will they push each other down to the 70's by forcing errors on each other? In general, what does it mean?
