If he makes his bends while the metal is still about 600 degrees, he might achieve a sharper angle, but I've done this many times and unless you use a heat stick or some kind of temperature sensing device, it is very dificult to get the right temperature to find the bending moment without going too far and getting grain seperation and tears, which he may or may not easily see, but will probably show up nicely at the first hard landing. I don't have a problem being corrected when I am wrong, ignorant, or un-informed about something.
