^because they wanted it to be exactly 1.5 times the damage from one tick of other mimicks.

for example, one tick of Mimicked Sigil of Silence deals 100 / 200 / 300 (+0.65% AP). multiply it by 1.5 and you get  150 / 300 / 450 (+0.975% AP).

The did it because they wanted the dmg to be exactly in the middle between one tick of the other mimicks to two ticks.
