HD4 · Tech / Flex

Only exists in pools with four or more Hidden maps. Most picks resemble HD3: tech, streams or flex maps under Hidden. 944 maps from 347 tournaments. Median 6.24★ (middle 80%: 5.2–7.2★), 2:46 long, 178 BPM. 87% of these maps come from quarterfinal-or-later pools. Collected from 1,591 osu!standard tournament mappools listed on osu!collector. A map's slot is its position within its mod bracket in the pool (the third NoMod map is NM3). The skill in the title is what this slot traditionally tests, but every tournament pools differently, so many maps won't match the label.
