Like I said, that is only relevant if your sport is lifting as heavy as load as possible one time, which is highly technical and takes many people a number of years, if not decades, to do properly under heavy relative loading. Most people technically falter under extremely heavy relative loads and of course you will need significant practice to improve this skill (just like most people have a hard time maintaining relaxation, complete extension, pelvic position, etc. at top speed in a race). It isn’t so different from improving speed where it’d be pointless to have say linemen doing flying 30s from a 40-50m run-up on Super-X mondo or doing Fast/Easy/Fast drills over 90-120m when they don’t need anything like that and it would likely hurt their development significantly, if they even survived it to begin with.
