Fuel Injection - explain this to me like I am 6 years old

everyone you talk to will say EFI won't make more power then a carb and its more about efficiently and drive-ability. but like that video shows thats only when the carb is perfect to your present conditions.. i think they could have messed with the carb a little more and got the power to match the efi but the next day when it was say more humid out and temps were different the carb would be off and th efi would be dead on still..
