Big injectors with small pulse width

So it seems like the trend is continuing to go larger on injector size while keeping pulse width low. Just today I saw fleece dyno’d a truck at 700hp on 250% over injectors, a stock cp3, and a fleece cheetah turbo. The truck ran clean as a whistle and it really got me thinking.

From what what I understand this makes things easier on the motor while still allowing for great power potential but is there a point where the injectors are “too big” and pulse width can’t be lowered anymore? How large can one go on injector size before cylinder wash down starts becoming a problem if the truck is street driven and sees some idle time? At what point does idle cleanliness start to become affected? Thanks for any info.
