I would suspect that the tuning is slightly off, introducing an additional friction component if all other factors (same shaft materials, field point styles, etc.) are the same. Do both bare shafts fly straight & parallel to each other out at 20-30 yards?

Great post!
But.... this conversation will quickly devolve, there’s no agreement between the light and fast s heavy and slow thinkers.
All I know is you don’t shoot a cape Buffalo with a 22-250 (light and fast) you use Something like a 416 rigby (heavy and slow).
All of the big animals that I’ve gone after have included some heavy thinking about heavy arrows and how to best tune them for perfect flight.
