In my quest for faster stages I have found that I should avoid the “all or nothing” approach to targets that require accuracy.
This means that at a match the 15 yard partial doesn’t get “hopers” thrown at it. I think there is nothing slower.
I don’t really think you can work out that this is slower in practice. There isn’t the match pressure and you have set it up so there is a better feel of how accurate you need to be.
Once that buzzer goes off accuracy and IQ is reduced.
