We are both saying the same thing - it's 50% in SP and 50% in Steem and SBD (the latter two's proportion keeps changing according to the economic logic of the developers - it's not just a formula, they change it by hand, from what I've seen).

The White Paper is written as vaguely as possible. This suggests to me and any investors, that the developers had no idea whether their project was economically sound or not, and they intentionally did not specify certain aspects clearly, which would allow them to tweak things as the system develops. This, however, makes the system rather vulnerable to market speculation - traders are not investing in the system itself, but are speculating on the economic knowledge and whim of the developers. Since modern day trading is all about analyzing widely available data and not the private thought process of a couple of people, this makes Steem rather unattractive (or rather - attractive for bearish trading).

That said, according to page 35 in the White Paper (which you've linked), it seems that the daily pool is generated in Steem. There's also a mechanism for reducing the incentive for mining Steem after a certain block number.

Think about this - either the developers had a perfect vision for the future of Steem and knew at which exact point in its development significant inflation (or oversupply of Steem) would kick in (it's now obvious they overestimated the popularity of their project and actually didn't have a good idea), or they have very bad ideas about programming (hard setting variables is a no no for most programmers) and economics (which no one on this planet fully comprehends; what they've did is put a flag in the middle of a river, over which they now have little control).

Anyway, it's a long topic and I'm grateful for your comment!
