Based on what I read from your posts (I'm not going through your code with my layman eyes), it's a clever system indeed. 

It allows most of the coins to be generated years or even decades later after (hopefully) the coin has gone mainstream, rather than being too concentrated in the hands of people who join in the early years. At the same time, it still gives early adopters pretty good reward to kickstart the system.

People worried about inflation needn't be. If the block reward scales linearly with total hash rate, it would just indirectly peg the value of the coin to energy cost/hash in the long term. With less than linear scaling and reward down to half every 9 months which is faster than energy cost/hash will come down guessing by Moore's law, the coin's value will be well beyond the electricity cost you put in now IF it ends up being widely adopted. Just don't dream about becoming a billionaire.
