A curve consists of ten points (in fact eleven, but the first one is at zero rpm). You can define them by setting rpm and advance wherever you like.
If i.e. your rpm range ends at 8k5 you set the last point there or maybe at 9k and additionally set the rpm limiter.
Between the points the ignition will interpolate.
