I think that is somewhat of an overstatement. If the brakes were 80% useless the car would not be drivable.
Newly turned drums and shoes that have been working in those drums are pretty close to as good as it gets. Arcing the shoes might give you that last 5-10%. The high spots will wear down quickly (BTW, even with arced shoes or shoes that have been in the drums for 10,000 miles you will STILL hear some high spots when you spin a wheel). If you are happy with the way the brakes feel, if you can slide all 4 wheels in a panic stop on dry pavement, I wouldn't worry about it.
