Heart issues and bypass surgery recovery: what to expect?

I’m trying to figure out how much permanent impairment is typically assigned after having four stents installed, especially since there are still two more left sitting in my arteries.

According to what's listed in the manual regarding

minor impairments range from 50% to 60%,
moderate ones fall between 60% and 70%,
and severe cases go from 80% all the way up to 100%.

Given everything, I’m honestly just not sure which category my situation actually fits into!

I am not entirely certain, but I suspect anything below average won't suffice, though it might be difficult... I cannot say for sure.

I ended up at 80% following my surgery (three bypasses)
