LF 100% with autoprice

I have hubbed DTW and am flying to big cities and small cities with big planes and small planes. After opening the hub I have noticed that autoprice tends to make the loadfactors go all the way to 100%, which is kind of nice but somehow seems wrong. When I first create a route it gives a more realistic loadfactors, but when I open more routes the older routes sort of creep up to 100% LF. Not all routes, but most of them.

Looking at the route information pages with the pie charts of routes with 100% LF I notice something weird. For example, DTW-ALB with 1X ATR-42, it says:

O&D passengers 70%
Connecting passengers 30%
Unused capacity 61%

O&D + connecting is always 100% and then there is additional unused capacity. That can't be right, or is it just a problem with the chart?

just a problem with the chart. I'll put it on my list.
