I think you need to smooth that curve out more. I'm not sure how well you can smooth things with the handheld but with the laptop you can select an area with the mouse and then smooth it out. I wouldn't run a curve like that in an engine since the timing is jumping 3 degrees in 50 rpm. I think that would be hard on the engine to have the timing jump around like that although the load is light in that area so it might not matter too much.
