+X to Y Modifier Tier Rating

+X to Y Modifier Tier Rating is the calculation method for reducing Y tags，(Raising Modifier Tier Rating excludes lower tier Modifiers from rolling, distributing their roll chance among higher tier Modifiers of the same Modifier type)，formula 1 - 100/(X + 100)。

+100 will cut off the bottom 50% of the Y tag's affixes, +200 will cut off the bottom 66% of the Y tag's affixes, and so on. The weight of the reduced affix will become 0.

Y Modifiers are X% scarcer

Y Modifiers are X% scarcer (Modifiers that are 100% scarcer have weighting halved), formula 100/(X + 100)

X% increased chance of Y Modifiers

Formula (X+100)/100。
