I really don't understand what you're saying! How do you get your percentages if not by getting each corner at the right weight? I don't know what the best percentages are, you seem to be an authority on that, but I know how to get the corner weights right from the percentages you said he needed! Knowing the correct percentages is great, but it's my opinion, if you don't need to spend a lot of time calculating them, the corner weights, it's also a big advantage.
Let me ask, if you have the percentages, how long does it take you to calculate how much weight you need on each corner? My spreadsheet takes less than 10 minutes, probably 5 minutes. And there's no calculating whatsoever.
Best thing, I give it away. lol
