I think that's a fair assessment too, I was just finding it interesting that I was stuck around 1650 for so long and there has been a jump to 1950 now without that much of an issue. I don't think my play is 300 points better than it was before.
It would be interesting to see what your true rating was if you played some more games!
Are the higher chess.com tactics under rated? I've jumped from a pretty much static 1650 rating for the past few months to 1900+.
I don't I've gotten that much better at tactics, to be honest it seems a lot of the higher rated ones are surprisingly over rated. There was a 2175 rating that was quite simple (and the comments said similar). https://www.chess.com/tactics/163574
Seems like there's theres a steady set of difficult questions around 1600 and then not much of a jump/decrease in difficulty after that?
My experience has been that there is a big spread of what I personally find difficult in terms of puzzle rating (I get puzzles I cant solve at 1700 but get ones that are easy at 2450. I'm not that surprised as there will be some variation in what tactical motifs I am better at but I think the answer is the number isn't supposed to represent how HARD a puzzle is, but how well a person of that rating would perform.
Ratings are more that just a result of tactical skill. A strong strategic player who has prepared a few lines will often beat a strong tactical player. The end result is that stronger players may not get certain puzzles and then the puzzles become ranked higher.
The other side of it is the numbers are just the performance stats from the site. I' consider myself about at a 1450 player, but my tactics rating is much higher. I don't think this means my tactics are as good as an average player of that higher elo .
