I want to beemind goals where spikes occur less frequently than 10% of the time.

Sample data series for a goal where the target value is greater than the starting value.

.1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .2 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 -4 .1 3 1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1 .1

For this goal, I would want the center line of the road to be the straight-line path from the starting value to the goal value, with a minimum road width of 8.2. I would get the motivational benefits of the purple line and the tourquoise swath, I would fee happy about being in the correct lane of the road, and I would feel pressure to return to the right side of the road if I crossed the centerline.
