I would take a somewhat different approach in order to get a blend of speed and precision. First, I would cut the fixed blade very wide and open, regulated for about 30 yards. That would be my fast/up close sight that would be ready in an instant. It would look something like this sight, on a well-used .458 Win that was the every day carry gun for a Zimbabwean PH who specialized in buffalo and tuskless elephant. A sight like this facilitates shotgun-like snap shooting, and will still be useful in really dim light.

Then I would cut the first blade with a very fine notch, regulated for not much further--maybe 50 yards. Sometimes you need to thread a bullet through the mopane and only have a tiny window, or maybe you see a dandy tiny antelope, like a duiker or a klipspringer and have to hit a target the size of the palm of your hand. So the first folding blade gives you the lateral precision to make such a shot.

This lousy photo shows how I cut the sights for my 9.3x62. You can (barely) see the lighter colored outline of the fixed blade and its wide V-shape. But then there is the first folding blade with tighter square notch, but having the much the same height, is regulated for the same distance.

Some people think about regulating multi-leaf sights only in terms of distance. There can be more to it than that.
