Shooter Lag

Also remember that the available voltage will not always be 12V and will vary depending on your battery condition and how much power the rest of the robot is drawing.

I think the best way to go at this problem is by combining the efforts of both the mechanical and the programming sub teams. If a shooter was designed in way such that only 85% - 90% of its power will ever be needed, then you could shoot your first ball at the "full" speed (say it's 85%) then second shot could be shot immediately by changing the shooter speed via programming to 90% and so on...

I would imagine that due to the loss of momentum, running at 90% would be similar to running at 85% when the time between two successive shots is small. Yes?

That was the intent of the bolded portions below:

#2 is so that your closed-loop speed controller has some "headroom" to apply more power (increase the applied voltage) to get the wheel back up to speed quickly

Best bet would be to delay the balls till the motor hit your ideal speed and your aim angle is correct. If you fire up 3 rapid balls that had the aim angle/motor speed off you have wasted 3 balls. Take a shot and see if it goes in then take another.
