cooldown is reduces by a percentage of its remaining cooldown.

With 6 missiles and ready:
 * 1st missile: minus 20% of remaining cooldown (80% left)
 * 2nd missile: minus 20% of remaining cooldown (64% left)
 * 3rd missile: minus 20% of remaining cooldown (51% left)
 * 4th missile: minus 20% of remaining cooldown (41% left)
 * 5th missile: minus 20% of remaining cooldown (33% left)
 * 6th missile: minus 20% of remaining cooldown (26% left)

And 26% of 20 - 8 seconds is -  seconds of cooldown remaining.

With 12 missiles and ready:
 * 1st missile to 6th missile: same as before
 * 7th missile: minus 20% of remaining cooldown (21% left)
 * 8th missile: minus 20% of remaining cooldown (17% left)
 * 9th missile: minus 20% of remaining cooldown (13% left)
 * 10th missile: minus 20% of remaining cooldown (11% left)
 * 11th missile: minus 20% of remaining cooldown (9% left)
 * 12th missile: minus 20% of remaining cooldown (7% left)

And 7% of 20 - 8 seconds is -  seconds of cooldown remaining.

This does not consider any potential intervals of time between each missile.
