Exactly. The only way you know for sure you have a load capable of shooting a 200/200 is to shoot 10 shots and put them all in the 10 ring at distance. Then you start trying to increase the X count. 200-10X to 200-15X to 200-20X. But you gotta shoot 20 shots to know for sure what the X count potential of that load really is. All the load work up techniques attempt to reduce the time and effort to get to that point. But in the hands of different reloaders, art gets mixed in with the science and all the details of brass prep and projectile sorting and so on suddenly matter, so my art might be different from your art. Even with 20+ shots of load work up, all I ever know is that a load has promise. Until 20 shots are on an F-Class (or another appropriate) target at distance, I still don't really know.
