Please critique my home front-end alignment method

I use two magnetic angle gauges, one on the disc and one on the spindle flat. Then for toe a piece of 1” angle 30” long clamped to disc each side then measure front and back. I got 5* camber 0* caster 1/8” toe. I also use struts where shock is then get correct distance from lower ball joint and T Bar flat per SM. I also have adjustable struts to gain more or less camber. This is a race car only.
