Is it just me, or did the hard puzzles get a lot easier?

I've noticed these last few days that I have a very easy time solving the hard tactics puzzles(often I just see the solution right away), whereas a few weeks ago I usually had to stare at them for a minute at least. I doubt I got that much better because my puzzle rating is roughly the same as it was. Anyone else notice this?

I also think so as I was 1900-2000 tactics rating for quite some time and now I suddenly increased to 2200 in it.Puzzles have got to have become easier.
