I could have sworn you recently started yet another thread on this very same subject where you recommended 800dpi @ 1000hz polling but with sync set to off, and both smoothing and sensitivity set to their maximums, using a ballistic curve to alter the sensitivity.
Whats it to be? You seem to come up with something new on a daily basis, making grand promises that it's perfect, and yet you clearly aren't satisfied with it, otherwise why keep altering it. I have no doubts that you spend a lot of time testing your theories, but they seem to change on a daily basis!
