Expected reserve = E[Y] - E[X] = 10 - 4 = 6

Estimated Ultimate L(x) = (5-4)*0.9+10 =10.9
Reserve: L(x) - x = 10.9-5=5.9 < 6, hence the decrease
thanks that makes sense

So if you use a formula with a certain set of weights, you are implicitly making a statement about what you believe the variance relationship is (because if you believed it was something else, you are stupid for not using the MVUE for what you thought it was).

Just passed 6, will start on 7 early next year.

Any recommendation on what material I should use?

TIA? CF? Rising Fellow?

A lot of people have been saying the CF/RF combo is the way to go. I'm sticking with TIA since for 5, 6, and 8 I only used TIA and it worked well for all 3.

Is this the CF/RF combo? Would it be sufficient to use it as the only material?
