The only exception were two orders for friends that I delivered personally.
They can't account for 6%.
Yes they can. It's how math works.
Total orders completed correctly divided by Total Orders multiplied by 100 = 94%.
a smaller number of orders, means those not correct take up a bigger percentage.
18/20 = 90% = 2 orders equals 10%.
58/60 = 96% = 2 orders equals 4%
