Wonder how this EVA and HIT stat work

I did experiment with Taiyi, whose basic EVA is 66.5 while my HIT of Panda is 123%.

And tried several times. Taiyis Eva is at least 88%, because of his passive skill 12% + Hourglasses bonus eva stat 10%.

While my panda doesnt have any buff, passive skill or bonus to get HIT.

But anyway, Taiyi never win against panda. He cannot evade from quite low hit attack.

I don’t want to think that this EVA stat starts working after 100%, because Its really hard to raise. But It seems not effecient and effective, even there is more than 50% of stat gap between attacker and evader.

Seldom Taiyi evades, but Its rare. And Its not 100% of evade, I mean It seems more likely to damage reduction. So even hard to deduce that he evades with 65%(88%-23%) of chance. Even Torvas-taz, whose Hit is 103%, also can easily beat him.

Wonder how this HIT and EVA stat work.
