I rapid fire through the first magazine, do a quick magazine change and rapid fire through the second mag.
I was once asked if I would rather be in the State next to ours where type III firearms (full auto) are allowed. My answer was "no, I don't want to spend my money that fast."
A IDPA stage (18 shots w/ one mag change) will be over in 15 to 20 seconds. I enjoy shooting and like taking my time to improve accuracy. I usually spend hours at the range shooting, you will be there a matter of a few minutes at that rate or a half hour at the most.
"Real World"??? Sorry, I do not recognize the planet you are from where paper targets shoot back at you. (A dead center hit is much better than 10 near misses)
Just my view on it.
