That is why CPF is confusing.

There are 2 dimensions.
1. The amount you want to participate in CPF Life....BRS vs FRS. BRS is half of FRS. BRS = basic retirement sum.

2. After you choose the amount,  you select between basic cpf life vs standard cpf life.

You can choose BRS + Basic; FRS+Basic...etc 4 combination.

In the above example it illustrate FRS+basic vs FRS + standard...meaning the participation sum is same.

To understand alone is complicated never mind making the right decision. Most people don't bother.

Hope I answered the correct question.

You are not exactly correct. CPF Life has more combinations than what you mentioned.  For example, there is also ERS with the 3 combinations i.e. Basic Plan, Standard Plan and Escalating Plan.
