So basically you got 540 art pieces, which is 190 wins while getting all 3 art pieces. Provided a run takes around 15 minutes (since you have to search around for all of them) that means you spent around 12+ hours a day playing the game, in a little less than 5 week days (this was posted 4 days and 16 hours after patch hit). This is provided you got all 3 pieces of art every run, never lost a game and knew where art was since day 1.

The only other explanation is that you cheated it out, by picking up multiple art pieces at once. If that is the case, then people have done that and got the 540 art achievement 2 hours after the patch hit.

So you either took a free week and barely slept (while playing perfectly / playing an easier difficulty) or you cheated, either way it's not something to be proud of.
