David,
It's jerky because the interpolation points between two pairs of x,y coordinates represents a segment ax,ay bx,by. Given that you can't use expressions, you can't force it to follow the points on the circle. If those points were drawn, they would represent a dodecagon. The arcs are really deflating to midway and then inflating until they reach the next proper hard-coded pair. We can call that the seasick effect.
The only way I can think of to overcome that problem is to have 360 arcs instead of 12. On a 1 degree basis the effect may be unnoticeable. Maybe using 60 arcs would also do the job. But then again, it's so much easier with scripting.
