I'll try to explain my calculation.
your ship : 569.475.255.375 hp / 656.368.839.235 attack / 99% acc / 71% abs
enemy ships : 11.728.750.000 hp / 238.598.036 defence / 45.871.066.607 attack / # = 53
calculate total defence enemy ships: 238.598.036 * 53 = 12.645.695.908 total defence
your first attack : 656.368.839.235 *
99% acc = 649.805.150.843 total attack
The enemy fleet must have had 75% absorb power.
total attack * (1-
0.75) = 649.805.150.843 * 0.25 = 162.451.287.711 attack
Then deduct from this the defence the enemy ships have:
162.451.287.711 attack - (238.598.036 defence * 53)= 149.805.591.803 damage
This explains why you did so little damage in your first attack. (I know the number isn't exact but I'm close enough to confirm that the calculations are correct)
Reason why your first ship got destroyed:
enemy ships total attack : 53 ships * 45.871.066.607 attack * accuracy * (1 -
71% absorb) = ?
suppose the
"accuracy" off the enemy was 40% (I'm allmost certain it is more than that)
=> total attack = 690.451.294.569
Your ship had only 569.475.255.375 hp => lost ship because less hp than enemy attack.
The rest off the battle is the same. (I hope I didn't make any mistakes)
