I've come across a problem during the fine-tuning of my object tracker. When the "neck" servo is steadily decending positions (turning to the left) the movement is smooth, even with decrements > 1. It acts completely different when turning right. There is a distict pause between each SERVOPOS and I noticed it takes longer to process a debug cycle as well. The head shakes, rattles and rolls, the values used to adjust turning speed based on object distance are insufficient, and it just looks terrible.
