Use the recommemded pitch curves, in 3 and 6g mode, check servo links measurements, they should be almost equal, if one is not, check servo horn at mid stick, some servos horns when assembled were not at 50% travel or are off, unscrew that servo horn and try to get it perfect by eye, that they all look the same at mid stick, if not, then that's why the difference between servo links, compensate that, either unscrew servo links in or out. IF you dont want to unscrew servo horns or if they look OK to you, then don't play with the links measurements, they come almost perfect from factory. Don't try to get the swashplate level with servo links, we are focusing on blade tracking here, to level the swash is the controller.
Check blade tracking, third value on your radio settings should be 50% on both, 3 and 6g mode.
Some people use 51-52 or XX%, different findings, different approaches, nothing is perfect.
