Honestly, if I had no understanding of CPFL and just read this article, I would be more confused than before I read it!
I think a better way to compare these is to run a side by side analysis between RSS, Basic & Standard... i.e. no pooling, partial pooling and maximum pooling. Notice I don’t say full pooling for Standard - although 100% of the premium ‘theoretically’ goes to the pool... from a ‘practical’ standpoint, the premium stays (to cover payments and bequest, until exhausted) and 100% of the interest earned on that premium goes to the pool - hence the 0% return until exhausted.
