I've flip-plopped on this so many times my neck hurts. Then I thought of a picture of a cam profile being shrunk. All the proportions remain the same. Then it hit me - lift is absolute. You can shrink the base circle so the lift remains the same and "fatten" the bottom of the lobe so the duration is the same. What has to give is the ramp from base to tip.

And maybe that's why many don't like them. May they strain the other components.

So both sides were right.
