I calculated the number of beatmap-sets per year for osu!std based of your packs.Elessey wrote:
How many maps per mode/year?
I don't have any stats. If someone is interested in doing that, I will put them here.
Of course I can't guarantee that they are 1000% correct, but they should be close to.
Also please be aware this are the numbers for whole beatmapsets only, as I am not crazy enough to count every single beatmap to ever exist. Well, I still did it for 2007 and 2008 though (see numbers in brackets).
2007: 199 (348)
2008: 698 (1858)
2009: 1430
2010: 1910
2011: 1427
2012: 1501
2013: 1232
2014: 1142
2015: 1533
2016: 1291
2017: -
