Interesting practical investigation! I have tried to translate the numbers to what is of interest to some of us, in order to get an idea about the numbers. The conclusion is that if you have a 8x Block system (58mm blocks) an go from a 10mm to a 5mm line you get approximately the same force reduction as if you keep your 10mm line and switch to a 10x block system. The reduction is about 10 % in each case.
