I think 104-week time interval makes it hard to sell the steemPower contract to customers since 104-week is not a short time period to average people.
What about diversifying steempower products according to time period?
Let SteemPower = Sp
Sp.x , x represents time(week)
Sp.x inflation compensation(%) = x/104
ex)
SpProducts = {Sp.8, Sp.13, Sp.21, Sp.34, Sp.55, Sp.89, Sp.104}
Sp.8 inflation compensation(%) = 8/104
Sp.21 inflation compensation (%)= 21/104
I think it will bring short term speculators into the realm of steemit arena.
