Remember, it's always better to error on the side of less steep than too steep. The template is about the minimum that can be achieved with good flow attachment. I'm sure with good flow upfront, your initial angles can be slightly more steep, but the 22 degree max remains constant.
When you chop your roof, I'd make all your angles using conservative measurements in order to ensure attached flow.
