Do you/Boo feel this is the case regarding sprints as well? Obviously there is a point of diminishing returns, but say you increase your weight numbers(bench, squat, clean, etc.) yet in your first 30m your times aren't dropping at all, do you think you can use the same criteria of reducing >80% loads and upping the volume of low int. gs, medball, etc.
Increases in weight numbers can also come at the expense of other strength qualities, especially the elastic qualities.
