+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)。

X	cut rate
50	1 - 100/(50+100) = 33%
100	1 - 100/(100+100) = 50%
200	1 - 100/(200+100) = 66%
300	1 - 100/(300+100) = 75%
400	1 - 100/(400+100) = 80%

+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	scale
100	100/(100+100) = 50%
300	100/(300+100) = 25%

X% increased chance of Y Modifiers

Formula (X+100)/100。

X	scale
100	(100+100)/100 = 200%
300	(300+100)/100 = 400%
