A routinely applicable method was elaborated for the evaluation of the monotonous dissipation tests with a sensor well above the tip which needs only very short data series (2-3 minute long). The method was extended to other filter positions and for non-monotonous dissipation test data, later on. In this paper some long and short, non-monotonous u₂ data series are analysed. It is found that even the first, increasing part of the non-monotonous data may give useful information on the value of coefficient of consolidation c.
