Do you know the daily amount of STEEM added to the rewards pool? With that information I should be able to estimate something about what the final rewards equilibrium will be.
I've been closely watching the steem rewards decreasing, and I posted some thoughts and quick analysis of it today.

I don't have the formula on hand, so I'm not 100% sure, but I believe it would be 1/365 x current inflation x virtual supply x 0.75.
Is the 0.75 the author fraction? Or something else?
Yes, author/curator.
So that shouldn't affect the fill rate of the rewards pool...
The fill rate should be constant (adjusting for inflation).
