This servo uses linear regression to estimate current time and frequency error. The number of points used in the regression is variable (from 4 to 64 in powers of 2) and is selected by a long-term statistic of the prediction error. Future improvements could include tracking of sudden frequency changes (e.g. due to temperature variations), better stability of the error statistic when a large offset is corrected, options to set the speed of the adaptation, minimum and maximum number of points, or an option to prefer frequency accuracy over time accuracy.
