Maybe I'm just a little out of focus tonight, but I can't seem to make sense of any of this...
I've always used 1/4 cup of sugar to 1 cup of water for my hummingbird nectar; for a quick fill-up of the feeder(s), I add 1 cup of water to my 2-cup Pyrex measuring cup and bring it to a boil in the microwave; stir in 1/2 cup of cane sugar until dissolved, then add ice cubes and stir until they melt (or just let it sit there for a few minutes) and add additional water to bring it up to 2 cups. By the time I get the feeder cleaned up the "nectar" is ready.
