Suppose you buy 100 Steem and convert them directly into Steem Power. And then directly start powering them down. How long does it take before you can have 100 Steem again?
I believe you get 1% every week of the Steem Powers you have. So you might think it takes 100 weeks to have 100 Steem again. But you also get around 0.5%(?) added to your Steem Power balance every day. So each week the amount of power-down-payout also increases. Considering all this how long does it take to get your 100 Steem back out the system? And are there more factors to consider?
For the sake of simplicity, assume that the price stays the same during this period. I realize that with Steem this you should not overlook due to the high inflation of 100% per year. But price is very hard to predict anyway for a new system such as Steem, so I just ignore it for the time being ;-)
