> Changes to include:
> a) fixing the offer() bug where we never track anything past WINDOW_SIZE reads (doh)
> b) setting the reset interval to 10m as intended, instead of 1m
> c) increasing the UPDATES_PER_INTERVAL since they are cheap and this gets us more recent data
> d) decreasing the UPDATE_INTERVAL_IN_MS (amount to be determined in testing)  to increase response time
