Could be good to have 0.1f as a PSF like SLIDER_END_RATIO or something even more explicit.
Also, 0.1f * beatmap.NumSliders() is used twice and could be stored in a variable ?

(Also, beatmapMaxCombo seems to only be used inside the if, so you might want to move it inside ?)

if (_maxCombo < fullComboThreshold)
comboBasedMissCount = fullComboThreshold / _maxCombo;
else
comboBasedMissCount = std::pow((beatmapMaxCombo - _maxCombo) / (0.1f * beatmap.NumSliders()), 3.0f);
}
_effectiveMissCount = std::max(_numMiss, static_cast<s32>(std::floor(comboBasedMissCount)));
