AB: We compare ACRIM and PMOD total solar irradiance satellite composites during solar cycles 21-23. By assuming only random uncertainties of the TSI satellite data sets and their overlapping comparisons we determine the statistical uncertainty of two simple satellite composites, which are statistically equivalent to ACRIM and PMOD composites. We find that the secular upward trend of +0.047%/decade between the minima of solar cycles 21-22 and 22-23 presented by the ACRIM satellite composite is statistically equivalent to the -0.009%/decade trend between the same minima presented by the PMOD composite.
