The problem with using percentages in these contexts is that they refer to something seemingly intuitive, but not quantifiable, and therefore ambiguous at best and useless at worst. What does 5%-95% refer to? Time? Effort/energy? We don't know.

It is like saying that to lose weight 90% is about nutrition and 10% is about exercise. 90-10% of what, exactly? And what would change in my approach to diet/exercise if it was 80-20% or 70-30%?

I think vague quantification does more damage along the way to achieving goals than we suspect. Maybe 10% more.
