Besides as an experiment, I really don't understand the purpose of this coin. Anyone in finance or economics wants things to be as transparent and predictable as possible in order to make decisions that will cost you your life savings if you guess wrong. Currency isn't supposed to be unpredictable, it's supposed to be...easily predictable...or nobody will use it.
I haven't really looked in depth to the functions this coin uses, but it's either just going to be something random that averages out over time, hence making it just a regular litecoin clone, or it will actually be random and unpredictable, meaning terrible to use as a currency.
I can't get the point you are making - the exact amount of new coins generated is unpredictable, not CGA as currency. It has very predictable maximum yearly supply - which will reduce depending on how many people mine it. How much will it reduce cannot be predicted - why? - because we cannot guess upfront when and why people will mine it.
Random and unpredictable is exactly what Bitcoin's price is against fiat currencies - for the same reason - it is the result of the decisions made by many human beings and is not subject to any modelling - does this make you believe that Bitcoin is terrible to use as a currency?
