As far as I am aware, from my study of the global parameters on the blockchain - based on various sources of documentation (none of which are verbose or totally clear) - the figure you have pasted here is for the total rewards fund, including the inflation that goes to the worker proposals and witnesses.
The figure I have used is the one labelled 'pending rewarded vesting' which I have then split according to the percentage in the global params that denotes how much is awarded only to authors of content. I am open to being wrong in my use of these parameters because I have never seen them fully documented anywhere in a way that leaves nothing to the imagination - but I am not seeing that demonstrated in your comments here.
