The equation, BlockReward = 5000 * 143500/BlockHeight, is basically a function of the form f(x)=A/x where A is a constant (which equals 5000 * 143500) and x is the BlockHeight, and from calculus you have the integral of this function taking the form "A * ln|x| + C" where ln|x| is the natural log of the absolute value of x (where the natural log is the log of base e where e is 2.71828) and where C is another constant, and we can determine the constant C from a known data point like the one in the paragraph above where the total supply on block 201886 was 965150963. The resulting equation for the total supply of SmartCash (SMART) as a function of BlockHeigth is as follows (valid for blocks >= 143500).

Great effort, and very good information. Are you an economist or something?

Thanks for the help, very good publicity.
