This is starting to bug me .Setting up a rest that is not springy is easy when setting up a rest like a blade rest maybe not.Ok you start by setting up your nock at 90 degrees to the string with an arrow now with a blade rest to start to find the 90 degrees do use a non weighted no tip for the initial 90 degree setting or do you use an arrow with the point installed to get your initial 90 degree setting for the nock setting.With a tipped arrow the the blade bends a bit. What Iam trying say is finding the starting point for setting up the nock hope this makes sense.
