I have never done the low brace thing. I never saw any benefit to it. Do a good job at floor tillering and go straight to full brace is what I have always done, and have never had an issue with missing draw weight or over stressing a limb. I did make an Osage bow that I did a terrible job of floor tiller, I was seeing how fast I could make a bow, and went to full brace, the bow was way stronger on one limb. A few minutes of working the opposite limb, and problem solved.
