I present and discuss the fitting methodology I developed for very-long time series (2088-day-long). This new method was first used to fit low degree modes, ℓ ≤25. That time series was also sub-divided in somewhat shorter segments (728-day-long) and also fitted for these low degrees, in order to measure changes with the solar activity level. I have recently extended the fitting in several ``directions'': 1) to substantially higher degrees (ℓ ≤125), 2) to shorter time series (364- and 182-day-long), and, 3) to additional 728-day-long segments, covering now some 10 years of observations. I present and discuss issues related to this expansion, namely problems at low frequencies affecting the f and p_1 modes, and the inadequacy of the leakage matrix at higher degrees. I also present some of the characteristics of the observed temporal changes in the resulting frequencies.
