Fair comments, I did qualify the first point by saying it's approximate,
TBH as to the second, I did wonder - but based on @arcange's stats which I quickly triangulated with the highest paid out posts, it seems that the total pay-outs are taken from the rewards pool, which is topped up with that 520K a week, I have no idea why it's so much larger than the inflation allocated to it!
Still a work in progress. Just wanted to get something out for the day!
