Sure but if the system can get your arc length, work angle, travel angle and travel speed dialed and consistent before you even plug in a real welder that's a decent increase in the throughput of a vocational facility with a given number of welding stations because now a fraction of the training can be performed in the classroom.
It doesn't need to match muscle memory. It needs to lop off the first 10-20hr of actual welding where the instructor runs from booth to booth telling people to correct their arc length, angles and speed thereby increasing the efficiency by which welders can be trained.
