Will it matter that you used the exact amount of cheese on your pizza as specified in the recipe? Only if you're trying to win a bet with a snobby Italian chef.
Or maybe, just maybe, it will matter if you're on a mission to create the most precise, algorithmically-optimized pizza in the land. In that case, we'd say go for it.
But let's be real, most times, it won't matter. The universe will not come to an end because you forgot to sprinkle a pinch more oregano.
