Understand why excess launch costs more on fast greens
The instructor says a little too much launch generally isn't a big problem on slow greens, but is a bigger problem on fast greens because it's hard to hold your line. They explain that on any green with slope or break, a bouncing ball picks up off-line energy from the tilt, making the right line nearly impossible to hold, while that same launch is much less of a problem on a slower green.
