Odd crank cap bearing?

The bearings are correct and in the correct location as in the stock confirmation the the 1,2 and 4 bearings are smooth as per the service manual. It also says while the 1, 2 and 4 upper and the 2, 4 lower bearings are interchangeable, the 1 lower is not and has a radius on the front edge.
I read the link "inertia" posted to confirm the reason for the notch.
I also found the the 1,3 and 5 journals have 1 oiling hole, where the 2 and 4 have 2 which is probably why the bearings are configured the way they are.
