I agree with this a lot (and thanks Gilles for sharing!).

I estimate that I know the 50g way less than Gerald H, so I wonder how many years of problems I should solve before having a grasp of it.

PS: and thanks Gerald H to share your solutions, they provide nice inputs. I wish people would share their work often (I say this because in my experience many people don't share their work unless they know it is really good for many and that is a pity. See Gauss and his works, or Riemann. The same applies to small but potentially interesting works like little programs.)
