Congrats! Your lock picking skill is off the charts!
The "difficulty" of any given lock in the actual game is determined by a host of factors, including the player's perk assignments at the time of the attempt, as well as hard-coded values and modifiers that I did not take the time to replicate exactly.
In FO4—unlike, say, Skyrim—you can't even attempt to unlock difficulties higher than Novice without investing in the relevant perk. Rank 4 makes bobby pins unbreakable, effectively removing the fail state for the player, as well as making the puzzle easier by negating the progress lost by the pin being reset when broken. That feature is also not present in this demonstration.
