Going back to the original question, I did select 8 standards for both cases (single fit with "fit this group" and combination of fits with "fit all combinations"), which gives me 247 combinations (see Excel file attached). In the case of the single fit I get a R-factor of 2.0x10-3 whereas for the best fit from the combinations I got 1.8x10-3 (the weights of each standards are also different in both cases).
My answer is still the same. It is quite possible that I am not understanding your explanation, but it seems as though you are comparing the best fit from the combinatorial sequence with the individual fit that uses all 8 standards.
