Hi! In a race, when you call a power 10, do you call it two strokes ahead (Power 10 in two, that’s one, two,) or do you just call it?
I say it’s up to you, what you’re comfortable with, and what you see. With younger, less experienced crews you almost always call it in two because they need that “warning”/prep period a little more than an advanced or elite level crew would but as you start working with advanced high school crews, college crews, etc. you can almost always call it “on this one” if you choose to.
I tend to go back and forth with how I call it. If I can see another crew making a move or we’re running out of water to make our move, regain seats, walk away, etc. then I’ll say “on this one” because I don’t feel like I can afford to waste those two strokes where you’d normally say “one, two”. If we’re in a good position and I want to keep building on that then I’ll say “in two” or something similar because I think that it helps to maintain the pace that is (hopefully) already working for you and it doesn’t give that sense of immediate urgency that “on this one” does.
