A set of free-running timescales is generated using 9 gears of fa from the USNO clock ensemble. Cesium and maser clock phases and frequencies are characterized by global fits to first- or second order polynomials, and the timescales are generated from the clocks detrended frequencies using a variety of weighting functions. These timescales are compared to those generated by USNOs A.1, BIPMs ALGOS and TT98, and NISTs AT1 algorithms from the perspective of algorithm choice and frequency stability.
