When you press a screen element, there is sometimes an animation as the game transitions to a new state.  Without a delay between the commands that Ragebot sends, you would find that the animation was still playing when the screen was being read for data making it impossible to read accurately.


By default there is a 1.5 second delay after pressing a button etc before the next action happens. You can extend or reduce this time if required by altering the Click Delay value but in tests, anything below 1000 can cause mis-clicks on even the best computers.


To optimise performance of your computer, a good rule is to set instances that are gathering to at least 2000 because they do not need to be fast as most of their time is spent waiting.  .


It is also useful with the Bluestacks "Eco Mode" which reduces the frame rate of the game to allow you to run more instances.  In testing, a delay value of 1000 allows Bluestacks Eco Mode to be turned on and the frame rate set to 10. Depending on your PC, this may not be enough for you and you may need to increase the frame rate or the Click Delay value.


Slower computers will need larger delays. There is no "One size fits all" value.
