“That’s the genius of the 64/4 rule! Applying the 80/20 rule to the top 20% yields 4% (20% × 20% = 4%). In other words, 4% of inputs produce 64% of results (80% × 80% = 64%). This is the 64/4 rule. The 64/4 rule is exciting, because it means that you can leverage a mere 4% of your time, team, or budget to produce massive results—more than half, or 64%. The million-dollar question is—what’s in that top 4%?”
