Punched your numbers into Stu's and it seems they are way stiff. However, when bare shafting you really need to compare it to a fletched shaft. Don't worry about the nock position.
First off, if you haven't cut all your shafts yet, I'd shoot a FL bareshaft with the point weight you want to shoot. Are you using screw-in points or glue on with adapters?
Compare the fletched shaft with a bare shaft to see if the bare shaft groups with the fletched. Once you get this to happen you can fine tune the shaft from there.
Once I get the bare shaft grouping and shooting where I am aiming, I will start taking a little cuts off the shaft to stiffen it up so that it will be very slightly nock left. Adding flething will stiffen it some.
