2 billion bts * (1+20%) = 2.4 billion. 2.4 billion * 10% / 365 = 657,534 bts
That makes about 650,000 bts a day. To me, this has much much bigger impact than PTS, AGS, DNS merge.
Well, btc currently has about 10% dilution but it's also decreasing along the time.
If we have to pay high to delegates at the moment, at least we should decrease the rate along the time.
