thanks, but to be fair, there is more to know. For example, I wish I had hard statistical numbers on how the drops of the flick get exactly distributed over the flick area with which chances, and I don't have the tools to measure that. All I can say is that it's more likely to land in the middle (sweet spot) of a "range box" and the rest gets randomly distributed in the periphery of the center. It would be great if Nintendojo or somebody else did a more detailed breakdown, if at all possible!
This guy's super busy, (not sure if he has a squidboards) but it might be worth asking him. He finds coding variables like this and messes around with them. In this vid, he essentially raises the angle of the spread of the shots. There might be hard data about the flick spread.
