it's actually perfect logic
growth is growth. regrowth is something else entirely... in the context of bodybuilding.
take Joe Blow.. he's 5'9 220 at 10%, and that's the biggest he's ever been. can he do a 20 week prep and 'grow into a show' and come in bigger than he started?
of course not.
take his brother Jim Blow.. he's 5'9 220 at 10%, and in his last contest, he was 240 peeled on stage (he dialed back the drugs in the offseason and shrank a little bit to recover his health). can he start a 20 week prep and 'grow into a show', ending up bigger than he started?
absolutely.
growth vs. regrowth.
therefore, the concept of 'growing into a show' is not universal.. which makes it inconsistent at best, and disingenuous at worst.
