I'd like to ask about 3 disabilities.
If we added a third disability rated at 10 % disabling to our original example, we would take your combined value of 65 and look for that number in the left column of the combined ratings table. We would then look for 10 in the top row and find the number where the left column and top row meet.
That sounds complicated. What would my combined disability rating be, for example, if I had  2 disabilities?
If you had 2 disabilities, your combined disability rating would be 19 %.
