pub const ROUND_TRIP_DIVISOR: i64

Server round trip time is calculated as an exponentially-weighted moving averaging formula with a weighting factor. A factor of 0.2 places approximately 85% of the RTT weight on the 9 most recent observations. Using a divisor instead of a floating point provides the closest integer accuracy.
