What is the Percentage Equivalent of each Proficiency Level on the PMP Exam?

If PMI were to disclose percentage values for each proficiency level, then why would they move away from the old system (of publishing the score in percentages) to the new system (of publishing proficiency levels)?

So the short answer is - PMI does NOT disclose the percentage score for each proficiency level (Proficient, Moderately Proficient, Below Proficient).
