Rapid ratings deflated at the 2200+ level?

So I reached a rating of 2300 in Blitz a couple of months ago and took a pretty lengthy break from chess. In the mean time, I still watched chess content on YouTube and also played odds games against beginners and intermediates; as a result, it really felt like I got stronger as a player, and my performance against some irl people I know improved.

So, I figured, why not just raise my Rapid rating (which was 2200 at the time) to the level of my actual playing strength? Since I was 2300-strength a few months ago and am now even stronger, surely it shouldn't be that much of a challenge to get my Rapid rating beyond 2300, right?

Nope. I have played a ton of Rapid games throughout the past month, and I am hardstuck in the mid-2200s. Furthermore, a lot of the opponents that I'm facing also have Blitz ratings that are higher than their Rapid ratings. For example, I recently beat a Rapid 2250 whose blitz rating was... take a guess... 2700 (!). Obviously, that's an exception, but 2300-ish Blitz/2200-ish Rapid seems to be a very common combination.

Am I alone in finding Rapid tougher than Blitz? Or did genuinely get worse during the break and am just coping?

Rapid should be tougher. Much more time to find moves and less blunders
