I'm not good on explain the whole thing of this mechanic since i also didn't learn the full math of it's mechanic, So... I just copy-pasta from other source (the 1st line) :

"The reason for this counter-intuitive result is the mechanism known as overkill protection. Which runs: Whenever a ship takes a shot that would deal more than its maximum HP, she will instead sustain a random amount of between 50%-79% of her HP in damage. Critically, only the 75-79% portion of this range results in a taiha, which is effectively a 1/6 chance.

In other words, a ship stands a better chance of surviving being hit for 200% of its HP than a hit for 80% of her HP.

The reason Akatsuki survives more than Choukai is because she turns every shot into an Overkill roll and this has a 1/6 chance total to survive at orange; while Choukai has a much higher chance for being hit for 75-99% of her HP (which is NOT covered by overkill protection) and being knocked to red outright without the benefit of overkill protection"
