It is proved that the parameter K in the equation R = Kf0T0 (R-relative sunspot number, f0-number of originated sunspot groups, T0-average lifetime of sunspot groups) is not a constant, but that it is approximately directly proportional to the average lifetime T0 of sunspot groups. As a result the earlier forecast (Kopecký, 1980) of the maxima of 11-year cycles Nos. 22 to 26 have been corrected. The principal result of the earlier forecast has been proved, i.e. that in the first half of the 21st century the solar activity should be abnormally high. The 11-year cycles should display maximum relative numbers of 200 to 300.
