Add a stability shaft to resist putter twisting

The instructor explains that a stability shaft added to an already-high-MOI putter design combines with the head's toe/heel mass and a properly fitted grip to further resist twisting on off-center strikes, making mishits' effect on the putt next to nothing. They say the diagnostic is testing on Quintic: if the measured strike location is scattered across the face and the twist is significant, that points toward this route.
