In the scenario as specified, I think you're in the 72nd percentile.

Hm... OK, I think you're right about that. Being in the 72nd percentile is not nearly as bad as dropping down into the 30s. Rereading the original formulation I see that I assumed that the <110 population would jump up past me, while as specified they would just have a 30 point boost which would put them much nearer me but not past.

On an absolute scale, they're doing fine.

Unfortunately, real humans (such as myself) do not live on absolute scales. This is why we are happier to see our neighbor's salary cut than the both of us receive a raise but his much larger, and this is why self-assessed happiness of nations is only weakly correlated with wealth & not perfectly correlated.
