I think it's a valid and trivial way to solve any problem which deals with unbounded constraints which is achieving the maximum frame rate possible while plugged in charging. Thus to solve it we generally focus on achieving maximum performance on least finite energy constraint which is low power mode. And we project that conclusion as it is performing it's theoretical best in unbounded mode thus the 120FPS challenge title.
It sounds like a click-bait, when you titling your article as "The 120FPS Challenge" and then "really going to do the 60fps challenge"
