something vague

I can't seem to put my brain around this OCW method of load development. I understand what to look for and the idea behind it but the instructions for creating my set of cartridges seems weird to me.
Doesn't this sound like you are testing the upper end of the load data? Now in my experience I have found that my most accurate rounds are coming from the lower to middle end of the load data. Maybe this test was form of load development isn't design for target shooting but geared more toward hunting? I've many great things about this test but just don't know if it would work that well with my rifles. What am I missing.

4. Back away from the maximum charge by 7 to 10 percent, and load one test round with this charge. Add 2% to the charge weight, and load another cartridge with that charge. Load a third test cartridge with the next 2% graduation. You will use these three cartridges for sighters, and more importantly to determine pressure tolerance in your individual rifle.
5. Add another 2% or so to the charge level used in cartridge #3 of step 4, and load three rounds with this charge weight. Add .7% to 1% to this charge, and load three more. Add that same graduation again, and load three more. Continue adding the chosen graduation until you have moved ONE increment above your chosen maximum powder charge.
