I suspect you are right.  But this is just where using the schema that
differentiates three levels of partial bf
    >80% / 20-28% / >20%
would help us find out the answers to two important questions.

IS there harm in giving just an occasional formula feeding?
IS there benefit in giving just an occasional breastfeed?

My guess is that the answer is "Yes."  Just knowing these answers would be a
help, even if we can't tell a mom how much virtue there is in nusing 50% of
the time vs. 30%.
