i know several good DIY guys that open one bleeder screw at a time amd wait until they get a solid flow of brake fluid out of it and then do the next one,
I was taught when bleeding brakes with the older single piston master cylinders to start bleeding at the right rear and then do the left rear, then move up to the right front and then finish at the L.F. the one closest wheel cylinder to the master cylinder
I do the same way on the new dual piston M.C., bleed the farthest one first and then do the closet one to the MC, front or rear first doesn't matter to me
