↑As of DE CU11, the bonus actually makes every second blow of Short Swordsmen line commence twice as fast, as if the rate of fire (RoF) was 0.75 seconds instead of 1.5 seconds like a generic Short Swordsman; however, every first attack's RoF is set to normal 1.5 sec. It also counts in the attack delay (AD) of a Short Swordsman (0.75 sec., unchanged for Romans), so the first two blows of the initial attack (after the AD) are dealt with RoF of 0.75 sec. Thus, Roman Short Swordsman, after reaching its target (the animation of the attack has just started), deals damage with the following cooldowns (every "→" means the damage is dealt): 0.75 sec. delay because of AD → 0.75 sec. delay due to increased RoF mitigating AD → 0.75 sec. because of increased RoF bonus → 1.5 sec. generic delay → 0.75 sec. → 1.5 sec. → 0.75 sec, which combines for 5.25 sec.; generic civilization would have 8.25 sec. instead. This lead to a slightly higher actual bonus RoF for the first blows.
