What new users of https://t.co/oOi48fvtQi and https://t.co/oRLTRckhyx need to grasp is when hard liquidations may happen during soft liquidations.
Yellow range is where your crypto converted to/from crvUSD. That causes losses and health reduction.
Hard liquidations are NOT at a certain price, but when health hits zero. Health reduces faster if volatility is high but slower as things calm down.
Health losses stop as soon you are above or below the yellow range.
