Correct the larger central bend first, and use the four spokes in the center of that bend.. like, 1/2 to 1 turn each loosening, on the outer side, and one turn tighter on each of the two that will "correct" the bend.
the two Other, opposite direction, bends will sometimes completely disappear after taking care of the larger bend.
up and down warping should also be considered.
that's interesting what you said about just start with the bigger bend. It does seem like it somehow works itself out as you start adjusting, like ironing a wrinkly shirt and the wrinkles push ahead of the iron like the cresting wake at the front of a ship and then they straighten out. I usually just pick one to concentrate on and so far it seems like it works out okay. I guess my confusion was determining when a wheel seesaws gradually between 2 extremes whether a) one of those sides is the straight spot to aim for, or b) if the straight spot is in between those 2.
