I know a national champion, Worlds contestant, and multiple record holder who says that in his Discus he always sets the speed to fly for 1 knot of lift. Unless the average lift is better than 10 knots. Then he sets it to 2 knots.

Flying slow costs very little time as long as you're not flying McCready 0 or slower. And you'll land out a lot less.
I find it difficult to believe he won a national championship flying a Discus using a 1 knot MC if the average lift was approaching 10kt. I don't have a Discus polar to refer to but I imagine the STF would be about 70kt ballasted for a 1kt MC setting.
In a nationals in a ballasted Discus would you recommend setting off from the top of a 9kt average climb at 70kt?
