    Thanks so much for the video. You are awesome.
    One small point of constructive criticism, (if I could be so rude) would be to use a note app with infinite scroll, instead of page turning. its really nice to always have the bit of work viewable in the video.
    Regardless, you are a legend.Thanks again

    Where's the exam from? This is not a standard style Actuary exam question; however, someone asked me to work through this exercise and I posted. Still good supporting/complementary info to know for the test.
