I would argue that the drag when using any fixed-blade prop is not "negligible". While it may be true that you keep up with, or pass, other boats, this is an "apples and oranges" comparison, and of little real value when discussing the performance of the prop. But if you can keep up with the competition now, think how you'd blow their doors off with a feathering prop!
