Floating Rate

srUSD operates on a cumulative compounding rate, which steadily increases it's price in rUSD. The price can never go below 1, but it increases at different rates as the interest rate on srUSD is updated by governance. Starting at an initial time, the cumulative compounded value of 1 srUSD is:

$(1 + r_{1})^{n_{1}} (1 + r_{2})^{n_{2}} . . . (1 + r_{k})^{n_{k}}$

Where the $n_{i}$s, are the time intervals between changes in the rate.
