Object tracking servo jitters... in only one direction?

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.

Object tracking with a SRF05 sensor

Motor ramping up and down

As of late, I had added some ramping to my motor driving code. I started with just ramping up but have added ramping down to stop as well now. Most hi-end motor controllers like the Sabertooth and RoboClaw do this for you, but it's nice to have on cheaper controllers to.
