I don't doubt you've tried many different ways. But have you tried many different ways to a statistically significant degree, then charted their success relative to equally-sized groups of other methods and against an equally-sized control group?
EDIT: Go ahead and make vague claims, but without showing your methodology and data, no one's going to believe you. Otherwise I can say that my secret sauce is to wait until I have 144, then buy two energy refreshes so I have 384, spend it all in one go, and it'll be a 5-pip gold speed arrow every time and MY claim will have more standing than yours, because at least mine can be tested.
