Attack Speed influence the amount of projectiles that are shot from the tower per moment of time. Attack speed value is number of projectiles per 2 seconds. Attack speed also increases the travel speed of a projectile from your tower to an enemy.
Once the 'Light Speed Shots' lab research has been completed, the projectiles will travel at the maximum movement speed possible, and therefor their travel speed is no longer affected by Attack Speed.
To get the value used in game, avoid any rounding.
Displayed Attack Speed = (Workshop x Lab x Card + Module Sub Effect) x Enhancement

Light Speed Shots Lab Attack Research Unlocks with basic Lab unlock at Tier 1 Wave 10 Milestone. This lab allows projectiles, once fired, to travel instantly to their target. A shot can be blocked by an untargeted enemy when the enemy is between the tower and the target. The untargeted enemy will take damage instead of the target.
