You are correct. "Slow down" was a poor choice of words. Perhaps I should have said it would"retain its position in flight", better(to relate it to the subject matter at hand....which is stabilization at longer distances).
But again, wouldn't it also slow down faster?
So....yes....but with a (possible positive) trade-off. Would FOC be coming into play?
I'm also assuming these two arrows would be shot from the same bow.
