CFA & Modern Portfolio Theory

What percentage of the overall curriculum (Levels 1,2 & 3), would you say is allocated towards Modern Portfolio Theory? I called the CFAi to inquire, but they said they didn’t have that statistic on hand and would have to submit an email for them to answer my question. I know there’s a good chunk. I’m at L2, and I know that L3 is primarily composed of portfolio management, which has its roots in MPT. So overall, what would you say the % is?
