I understand how the combined rating chart works. I understand that you start with the highest rating, and combine with the next highest rating, and combine with the next highest rating.

My question is: for every time that you submit a new claim, is the entire combination chart started over from all the ratings you have, or is your current combined rating used as the starting point for a new claim?

Example:

1st claim got a 50% and 30%, which combined to 65% and then rounded up to 70%.

If I file a new claim a few years later that gives a new 20%, do you combine 70% with 20% or do you start over and do 50% and 30% and 20%?

Can you provide supporting document?
