rake in degrees of the leading edge depends to the fin outline. A more triangle outline has more degrees at the leading edge than a rectangular outline meaning the same rake. So be careful if you compare different outlines!
But its true the range of the angle of the leading edge is from 2 to 6 deg.
more power at 2 deg, more downwind speed at 6
