In addition, your own definition of the perfect punt is likely to change over time, with your mood, experience, cash flow situation etc.
Meaning that "the perfect punt" is a fluid concept, and as such is effectively impossible to find. You'll always find something that wasn't perfect about a punt, even if it's someone small and irrelevant like you didn't like one of her tattoos, her oral wasn't as good as you'd hoped etc.
But, the fun lies in doing all the field work...
