In the summary of the 1main part of this work it was stated that all physical constants investigated there, like G, μ0 ε0 or α can be represented over only three basic values, i.e., a minimum length smin, minimum time tmin and the radius of the electron re, as well as additionally the dimension factors fD4 and fD42 worked out especially for the projection theory. With this supplementary work, we have now succeeded in reducing the number of basic values to a single one, namely re, since the other two can be derived quite easily from this quantity. The minimum length smin, which was previously calculated via h and therefore corresponded from the value of the Compton wavelength for the proton, is now replaced by smin = re 2π2. The values of smin old and new have a relative deviation of 1.6 10-6, which is acceptable, but still subject to further consideration. For the conversion of tmin to a re-based expression, one must remember the important principle of projection theory that time in our projective reality corresponds to a length in the 4th dimension. A length in the third dimension can be transformed into a four-dimensional one simply by applying the power 4/3. It was postulated therefore for our basic values: re4/3 ≡ tmin re4/3 = ftime tmin The task was to calculate the proportionality constant ftime in a simple and independent way. In fact, this was accomplished in three ways. The first formula is based exclusively on π and the above-mentioned dimension factors. The second equation is a pure number construct, i.e., a geometrical series which contains only powers of ten and the factor 60 which is important for our time calculation. The third formula derives in the basic structure from the second one, but contains the important conversion factors of our time division system (1440 min/d, 86400 s/d) and a time reference from cosmology, the sidereal year in sidereal days. With these proportionality constants, the speed of light could be calculated with a relative error of 2 10-7, 1 10-9 and 5 10-11 in the order of the above enumeration of the factors.
