It's actually 25% since there're 4 states; Fine/Shouha/Chuuha/Taiha. Not sure if it's rounded up, down or nearest though. Just use KCV/KC3 and you can check your ship's hp before you choose formation. Thus you can check if you've any Taiha-ed ship and if you do, hit the damn refresh button. It's too late once you chose a formation though.
