Consider new wedges around 100-125 rounds of use
The instructor cites Titleist research done with test robots that found rollout was significantly higher on wedges used over about 125 rounds, and suggests roughly 100 rounds is a reasonable benchmark. However long that takes for you - two, three, or four years depending on how much you play - is the point where you probably need to look at new wedges.
