StatsD daemon aggreate data, so percentiles and other values should be calculated on StatsD daemon side.
There is one more thing - Graphite reporter overwrites last data with new one, so if you use this package on multiple workers you get data only from one worker. StatsD aggregates all data from all workers making more sense, that's why it's not sending other than raw values for instruments.
