Effects described as “Increased Speed” have dimishing returns when it comes to the reduction in time per action, calculated as 1 - (1 / (1 + increased_speed_amount)). Essentially, it is how many more times you can perform the action in a given timeframe. At base revive speed of 3sec, you could do 20 revives per minute; 20% increase allows you to do 24 revives per minute (or 2.5sec per revive)
