I wasn't meaning to say one way is the only way, I was nearly stating that partial reps has it's place and full range anything has it's dangers by putting a lot of stress on joints. I suffer very badly with both rotator cuff damage, been like it for yrs as I too started out full range, even this with 30+db will cause a few nights of soreness and awkward pain, yet I can hit 50db on partial reps fine with only nominal soreness and Ive not noticed any size difference..
Like coldo say horses for courses in the gym hence why the magic formula hasn't yet been invented bottled and sold..
