Replace your most-used wedge most often
The speaker describes a "one, two, three, four" rule they associate with tour play: over a year, roughly one pitching wedge, two approach wedges, three sand wedges, and four lob wedges get changed. The point they make is that it is not just about the number of wedges but your go-to wedge, often the sand or lob wedge, is the one you hit most and therefore change most often.
