From your post, I surmise that you were not adjusting your body cant to match your bow cant at 45*, but were adjusting your body cant at 60*. You should adjust your body cant to match your bow cant at any but very small degrees of cant, and 45* is a significant amount of cant.
At first I thought you were not allowing for your cant in evaluating nock high, but on second reading I believe you were taking this correctly into account. In other words, you were interpreting a nock high right bare shaft at a 45* cant as being the equivalent of a nock high bare shaft with the bow held vertically?
