Same sort of idea. It IS possible to get level 4 throw before Derrick Man, (Only managed this because of the extra points because of the release of 1.2) and much much easier for the reasons stated above, I've also noticed that after you get a certain number of high level gags (For myself: Level 4 Throw and Level 3 Lure,) Derrick Man's cogs get stronger and have more in general, it's an RNG fest no matter if you get level 4 throw or not. Hope this helps (:
