It’s hard to improve something if you have no idea how to measure it. “Being a better fencer” is a worthy goal, but it is difficult to know if you’re achieving it.
We all want to be better fencers. If you don’t then you can stop reading here - but leave a comment at the bottom because I’m curious why you’re on this site. We train, drill, spar, compete, pore over old books and read modern fencing handbooks on the sly. All to be better fencers.
