> 100% ... all the time

Because nothing meets that standard, it's not an applicable measure of quality. Also, it tends to lead to binary thinking: 100% or null.

But we live in a world of less than 100%, and there is a lot of variation: Five nines, 80%, datasets with just a few valuable records, etc. That's where the real-life questions are.
