not quite. lets say you have 104k steem power. Thats not really steem, its something called vests. Your "interest" comes from the conversion rate between your vests and steem going up.
So as you WD your vests , each payment is going to get progressively larger. But at the end of the 2 year period, you will still zero out.
Also, youre making an error of thinking that you wd 1% of your balance every week. You do not.
You WD 1% of your initial balance every week. but that is a larger and larger portion of your remaining balance.
thanks for clearing that up, helps a lot.
